Hybrid tower means the tower with main legs are pipes and other members like bracings, horizontals and redundant members are angular members. Selection of hybrid tower is mainly due to three-legged configuration and pipe sections have less drag coefficients compared to four legged angular towers which resulting less wind load on tower for structure weight optimization. Lattice towers are light weight structures and governed by wind loads due to tower body, antennas and other equipment. Current industry practice for design of telecom structures from the available general structures building loading and design standards like IS : 875 (Part 3) – 1987 for load calculations and IS 800-1984 for design of pipe sections and IS 802 (Part 1/sec 2) – 1992 for angular sections design. Recently the loading standard and design standard has been revised IS 875 (Part-3)-2015 and IS 800-2007. So, it is important to understand the effects of new standards on already designed and installed towers using old codes and understanding the provisions of revised standard in line with the international design standards like ANSI/TIA-222G. 60m high 3-Legged Hybrid self-supporting telecommunication tower with X pattern bracing has been selected forthe study. This paper explains the codal provisions for calculating wind loads [IS 875 (Part-3)-1987 &IS 875 (Part-3)-2015] and members capacities [IS 802 (Part 1/Sec 2)-1992, IS 800-1984 & IS 800-2007] using old and new Indian codes along with American Code (ANSI/TIA-222-G).Comparison statements and conclusions have been presented at the end of the paper.","PeriodicalId":14258,"journal":{"name":"International Journal of Research in Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78276591","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 presents the reports of laboratory experimental investigations carried out in order to study on the development of High performance and high Strength Self Consolidating Concrete containing/using GGBS, fly ash, and cement as a binder and its effect on the compressive strength of concrete at standard water-cement ratio in self-compacting concrete. It is found that the compressive strength of self-compacting concrete decreases with increasing in temperature. It is compared with normal-strength self-compacting concrete to possess a larger amount of compressive strength of concrete which is exposed to high strength temperature. In the experiment, flyash was varied by 5%, 15%, 25%, and 35%. GGBS was kept constant at 20% for all mixes. Cement was proportioned as 75%, 65%, 55%, and 45% respectively.

Cognitive maps can be defined as a category of mental representation and concepts that are built to visualize and obtain information. The reason why people use cognitive mapping is to create an opportunity to represent their experiences about their environment. Public spaces provide a space in which people can come in contact with the social world outside and experience the opportunity of being with, seeing and hearing others which instills stimulation. This paper aims towards the role of cognitive mapping in spaces for public use. Besides, the relevance and impact of Cognitive Mapping in Public spaces is also discussed. The five principles of Kevin Lynch i.e. paths, nodes, districts, edges and landmarks are considered for understanding the impact of cognitive mapping in spaces for public use. Thereafter, the Influence of Cognitive Mapping in determining success / failure of a Public Spaces is also looked upon. Next, two cases of Mexico City and Melbourne, involving cognitive mapping in places for public use is mentioned to understand the practical implications of the topic. Lastly, observations from primary survey/exercise for understanding cognitive mapping in spaces for public use undertaken by the authors have been mentioned. These primary studies had been done in Jodhpur, Chandigarh and Visakhapatnam. The inferences and facts from the paper might be used by architects and planners to understand the considerations to be taken before starting to visualize a successful public place.","PeriodicalId":14258,"journal":{"name":"International Journal of Research in Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89307976","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}

The performance of a rocket is directly affected by the design of the solid propellant used. The presence of impurities in the propellant formulation can reduce the average thrust, specific impulse and characteristic velocity of a rocket. Oxidizers are the main compounds in propellants formulation, which produce the high energy on combustion. One the most commonly used oxidizers in amateur rocketry is potassium nitrate. KNO3 is normally used because of its good characteristics that include compatibility with others ingredients and availability at low cost in fertilizer formulation. The main objective of this work is to propose a methodology to obtain higher purity potassium nitrate from a fertilizer, an available and inexpensive source that can be used as oxidizer in a solid rocket propellant formulation. The KNO3 crystals were obtained by recrystallization process using a commercial fertilizer. The properties of purified fertilizer were compared with the properties of KNO3analytical. The fertilizer, purified and analytical grade KNO3 samples were evaluated by means of morphology, pH of saturated solution, Fourier transform infrared (FTIR) spectroscopy, and differential scanning calorimetry (DSC). The results demonstrated that recrystallization process effectively remove impurities from the fertilizer. The purified KNO3 crystals were optically transparent with a planar shape, similar to higher purity KNO3. The FTIR and DSC results showed that some impurities, such as, sulfur and alkaline compounds were removed after recrystallization and the purified KNO3 presented a similar behavior than higher purity KNO3. The recrystallization process used in this work can successfully used to obtain KNO3crystals with high purity that can be used as oxidizer in solid propellants for rockets.","PeriodicalId":14258,"journal":{"name":"International Journal of Research in Engineering and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85914608","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}
