One of the strategic approaches of integrating transport and urban planning is introducing an optimized ratio for administrative level job-house combinations. The objective of this research is to develop a computer-aided mechanism to assist the determination of development zoning regulations based on the job-house combination in a regional context. The R programming platform is used to develop the automated tool. The data required for the analysis are road network details, trip generation and trip attraction details at each Traffic Analysis Zone (TAZ). The gravity model is used to carry out the trip distribution and it is assigned to the road network using the graph theory. The centrality values are used to estimate the potential trip attraction levels. The main assumption undertaken in the study is that the trip generation occurred by a group of population in a particular TAZ is considered as work based trips. The result of the method for Colombo district, Sri Lanka indicated that the job-house ratio varies from 0.1 to 9.2 resulting in an average trip length of 23 km from houses to work locations. Finally, the method suggested a minimum and maximum value of 0.5 and 4, which reduced the VMT from 46% and average fuel consumption by 22% .","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"22 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":"131628395","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}

It aims to cooperatively assess the seismic vulnerability of primary schools of the Algarve (Portugal) and Huelva (Spain). Primary school buildings have been selected due to their low adult/child ratio and the fact that many of these buildings were constructed prior to the current seismic resistant codes. To determine the seismic behaviour of primary schools in both regions, this has been studied with building seismic performance analysis through the capacity-demand spectrum method. One of the main difficulties of the project has to do with the large amount of buildings to analyse. This paper is focused on obtaining and comparing the performance point of different types of buildings and different structural systems (reinforced concrete frames, unreinforced masonry walls and mixed). The goal is to be able to extrapolate the results from the buildings analyzed (type and structural system) to others where the information is not available. Different types and structural systems have been calculated and their seismic behaviours have been compared. The results show that the type and the structural system are outstanding for calculating the performance point and that an acceptable correlation can be inferred from similar types and structural systems. The comparison of the different structural systems for the same typology has shown that for the same shear force, the Reinforced Concrete (RC) frames buildings are able to get deformed significantly more than the Unreinforced Masonry (URM) walls.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"46 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":"130548891","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}

In the performance-based seismic design, it is essential to establish a universal and practical demand model. In this paper, to facilitate the use in practice, the probabilistic demand models are developed by adding linear correction term and random term to the commonly used deterministic models. Two types of demand measures, the bending moment and the axial force of the lining to transverse seismic load are considered. The uniform design method is used to generate the samples to calibrate the model parameters, and the uncertainties of ground motions, site properties, and tunnel dimensions are considered. The parameters of the demand models are estimated by the least square method. The probabilistic demand models established in this paper can accurately and reliably evaluate the seismic demand of the tunnel and obtain the probabilistic distribution of the demand, which is of great significance for the seismic vulnerability analysis of tunnel structures. ","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"50 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":"128240081","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}

Ceramic Waste Powder (CWP) is a by-product of the ceramic industry, resulting from polishing of ceramic tiles. The utilization of CWP will not only reduce the dumped solid waste and the required landfills, but it can also be utilized as a supplementary cementitious material in concrete, as a cement replacement, which will increase the sustainability and help protecting the environment for the future generations. CWP was used as a partial replacement of cement in different percentages (0%, 15%, 30% and 45%) with two W/C ratios (0.4 and 0.6). Fresh and hardened concrete properties were examined and tested such as (slump, unit weight, compressive strength, split tensile strength, absorption, and electrical resistivity). Also, the characteristics of CWP were investigated (chemical composition analysis, particle size distribution and pozzolanic reactivity). XRF analysis of CWP showed a good indication of being a pozzolanic material by having more than 70% silicon oxide (SiO 2 ). It was found that the introduction of CWP shows improvement and acceptable results in concrete properties. The optimum value of 15% resulted in increasing compressive strength, increasing tensile strength, reducing absorption, increasing modulus of elasticity and toughness, and improving electrical resistivity and corrosion rate. Higher values, up to 30%, maybe also used for greener more sustainable concrete with an acceptable reduction in properties.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"2 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":"133695063","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}

Results from the FE models were compared with experimental values. The effects of varying concrete compressive strength, projectile diameter, nose shape, and striking velocity on the penetration depth of the targets were captured. Two concrete constitutive material models, the Holmquist-Johnson-Cook and the Advanced Fundamental Concrete models, were implemented in the FE analyses for determining their suitability in predicting penetration mechanics with reasonable accuracy. In most cases, the finite element results were able to predict penetration depth experimental values within a total root mean square of 10% or less considering a wide-range of projectile striking velocities. Both concrete constitutive models were shown to be suitable for penetration mechanics problems.
