Machine foundations are the constructions which are intended for mounting on it a specific type of machine. The foundation has to transfer dynamic and static load from machine to the ground. The primary difference between machine foundations and building foundations is that the machine foundations are a separate structure, even if they are inside the building. Failures of machine foundations can be very dangerous due to its carry loads from machines in operation. There is also an economic aspect because every break in the operation of industrial machines is expensive, especially in the gas and oil industry, where technological processes are complex and multi-stage. Repairs to concrete machine foundations are problematic, so the capability to predict what exactly affects failures seems extremely necessary. The failure of concrete machine foundations depends on many factors that are not fully understood. Modern achievements of science and technology, especially machine learning techniques may allow determining what affects the failure rate. This paper presents an analysis with the use of machine-learning techniques to predict in which way loads can affect the failure of foundations. This study examines whether and what relations exist between variables describing loads about the machine concrete failures occurrence. The analysis concerned some variables such as cross-section reinforcement amount, the grate load, measured concrete strength, motor short circuit moment load, the engine unit and rotor with shaft load, the pump unit and rotor with shaft load, the weight of the foundation, total load with foundation self-weight. The primary parameter of concern is the failure occurrence rate.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128235963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper introduces two designs for smart autonomous shading systems that are implemented within building envelopes. In fact, they incorporate the shape changing smart material; shape memory polymer (SMP) in which its shape changing effect is triggered by temperature increase in a self-propelled manner. Laboratory experimentations are conducted to test both designs utilising SMP sample representing shading surfaces that can be attached to the building. The surfaces are flat; closing (providing shade) when the temperature is 35 degree Celsius or more and bend to open (allowing light penetration) when it is 25 degree Celsius or less. The experimentation verifies the notion behind the designs as a promising green alternative exhibiting preliminary success. This experiment is an exploratory trial towards investigating the possibilities of the applications of shape changing smart materials architecturally driven by the primal aim of saving energy. ","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121292583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recycled aggregate is produced by crushing demolished waste to reclaim the aggregate. For the past few decades the availability of Construction and demolition waste (C&DW) has increased so much that the concrete industry has begun utilizing it therefore reducing cost of aggregates. Utilizing C&D waste in structures decreases carbon emission and helps concrete industry to expand further without illtreating the environment. The objective is to study the mechanical properties (such as Compressive Strength, Splitting Tensile Strength and Flexural Strength) and durability properties (such as Resistance to Chloride, Carbonation and Freeze and Thaw) of concrete using reused aggregate. It is observed that the mechanical and durability behaviour of reused aggregate concrete (RAC) is secondary to that of standard concrete but with the using different admixture and different mixing approach, desired properties can be achieved. Moreover, it was seen that the improvement of the mineral admixtures to execution change of the reused aggregate are higher than that to the characteristic of natural aggregate. ","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126487218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess the sustainability performance, including energy performance, of buildings, Australia has developed several evaluation systems with the main ones being Green Star, NABERS, NatHERS and BASIX. Industry practitioners have a certain level of freedom to choose from these evaluation systems to evaluate the sustainability performance of their buildings. However, there is a lack of systemic comparison among these evaluation systems in general, and between the ways that the energy performance of buildings is assessed by these systems in specific. This study provides a systemic comparison between these four main evaluation systems regarding their approaches to assess the energy performance of buildings in Australia. The results show that these systems use different assessing methodologies, namely indicator-based or simulation-based methods, to assess different types of buildings based on data from different sources. These differences reveal the possibility of merging these existing systems to propose a new system that could better assess the energy performance of buildings in Australia.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"29 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128772327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to timber be a raw material, natural defects are present, what reduce its strength capacity and cause, in particular, brittle failures in the tensile region of timber beams. In order to increase the mechanical properties of these beams, fibre reinforcement can be applied. In this context, natural fibres, such as Sisal fibres, already used in various fields of construction, are an alternative for reinforcement of timber structural elements, by taking into account their adequate mechanical properties and, in special, for low-mechanical resistance wood species, such as Pinu sp, a species used widely in timber construction. This paper deals with an experimental analysis glued laminated timber beams (Glulam) of Pinus sp species, reinforced by Sisal fibres. Bending tests were performed on six beams with the following dimensions, 53 mm-width by 180 mm-height by 3000 mm-length, which were prepared with eight lamellas by 8 mm-thickness. These beams were reinforced with Sisal strips that were glued by Epoxy adhesive on the bottom part of these beams. In addition, comparisons of result with non-reinforced Glulam were carried out. From the analyses of the experimental results, a decrease of 20 to 30% for the normal stresses, 5 to 10% for the shear stresses and 8 to 12 % for the displacements in relation to non-reinforced beams were verified.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133948539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce disposal and pollution problems emanating from these industrial waste, it is essential to develop profitable building material from them. Recycling of such wastes and using them in construction materials appears to be viable solution not only to the pollution problem but also an economical option in construction. In view of utilisation of such waste in construction materials, this paper reports on the mechanical properties of utilisation of waste sludge obtained from Common Effluent Treatment Plant(C.E.T.P) in concrete. To evaluate the effect of dry sludge on concrete performance, its physical and mechanical properties were studied. In this research an attempt is taken to bring a comparison of the sludge waste in various proportions so that the final product property of concrete mixture is same as the reference (with 0% sludge) mix. Waste sludge material was replaced with cement in various percentages as 2%, 5%,10%. Reference concrete mix is also made for comparative reasons. To characterise the mechanical behaviour of the concrete, compressive strength test was conducted by means of Universal Testing Machine (destructive) after interval of 28 days, 90 days, 180 days respectively. Water absorption test was also conducted at interval of 28, 90 , 180 days so as to get an idea of change in the water percolation property of concrete. Tests results indicated the positive relationship between 2% 5% replacement of C.E.T.P. sludge with compressive strengths. The same results obtained for 10% replacement for Water absorption ratios likely to be unfavourable.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124217145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
