SEISMIC PERFORMANCE OF RE-ENTRANT CORNER BUILDING UNDER THE DIFFERENT EARTHQUAKE DIRECTION
Get PDFIn the modern area, Irregularities in building is common phenomenon. But because of increase in irregularity the structure becomes more vulnerable against the earthquake. In this study a re-entrant corner type of plan irregularity is considered. For the sake of study two G +7 R.C. frame buildings that is one regular and one plan irregular is taken satisfying the criteria given in IS 1893 (2016). Linear dynamic analysis done using Response Spectrum Analysis (RSA) and Nonlinear Dynamic Analysis done using Time history analysis (THA). For Nonlinear dynamic analysis, seven different time histories were considered and is applied in twelve different direction at an interval of 300. Linear dynamic analysis does not shows the much effect of direction of earthquake in terms of relative displacements. But in case of nonlinear dynamic analysis, the incident angle that produces increase up to 50 % in terms on relative displacements. From the analysis result it is concluded that one should go for the nonlinear dynamic analysis for the safer design
DEVELOPING A MODEL FOR EFFECTIVE CONSTRUCTION SITE LOGISTICS MANAGEMENT
Get PDFThe construction industry is often slower to adopt new technologies than other industries. Yet the construction industry shall embrace these technologies sufficiently in order to keep up with advances in other trades. One of the most crucial elements in construction management is productivity. And the adopting of new technologies such as mobile-based application can increase construction project productivity in such areas as materials management, tool use time, and labour motivations. During the project we studied and analyzed the data to investigate and improve the logistic situation at a construction sites situated in Pune. During the study we found that there is a lack of general knowledge regarding material and site logistics in construction projects in Pune. As a result, there are many unnecessary movements on site interrupting overall output on site and displacing direct value-added activities. Therefore, the purpose of this paper is by practical observations and site interviews, earlier studies, to investigate the existing logistic approach on the construction site, as well as to provide proper logistic strategy for improving construction process
COMPARATIVE STUDIES OF COMBUSTION, PERFORMANCE AND EMISSION PARAMETERS OF DIESEL ENGINE USING CASTOR BIODIESEL BLENDS
Get PDFThe experimental studies for combustion, performance and emission characteristics of the variable compression ratio (VCR) diesel engine of rated power 3.5 kW at rated speed of 1500 rpm at two compression ratios of CR-16:1 and CR-18:1 was done using castor biodiesel-diesel blends (B10, B20 and B30) as a substitute fuel. The results revealed that Start of combustion (SOC) advanced, End of combustion (EOC) delayed, Ignition delay (ID), Maximum Rate of Pressure Rise (MRPR) decreased while Combustion duration (CD), Premix Combustion Phase Duration (PCD) increased with biodiesel blends concentration. Increase in CR resulted in reduction in ID, CD, while MRPR and PCD increased as compared to plain diesel. Brake thermal efficiency (BTE) decreased with increase in blending percentage for both compression ratios (CR’s), while higher CR resulted in increase in BTE. Carbon monoxide (CO) and unburned Hydrocarbon (HC) emissions decreased, while Carbon dioxide (CO2) and Nitrogen oxides (NOX) emissions increased with biodiesel contents for both CR’s. Increase in CR resulted in reduction in CO and HC emissions while CO2 and NOX emissions increased. The castor biodiesel may be used as a substitute fuel by blending it partially with plain diesel in diesel engin
