Study of Steel Structural Analyses and Designs Using Time-history Analysis

Abstract

Population density in Taiwan ranks among the top in the world with too many urban populations and small urban land areas Therefore buildings need to be increased in height to increase space utilization In recent years the proportion of steel structures used in high-rise buildings has become higher and higher Compared with concrete steel has the advantages of high material strength but light weight and is suitable for high-rise buildings However Taiwan is located in the Pacific Rim seismic zone Earthquakes of various magnitudes occur frequently In order to prevent buildings from collapsing in a strong earthquake a more rigorous dynamic analysis of the steel structure should be carried out Ensure that the building can protect people's safety within the acceptable range under the influence of earthquake force This study discusses steel structural design using the time history analysis According to the offshore wind turbine analysis and design program WindTurb from the research team of Shen-Haw Ju the NORSOK N-004 turbine support structure specification is added to the program and compare with the original API specification The concept of time history analysis in the offshore wind turbine is then applied to the steel structure and developes ASDLRFD program The primary reference specification is ANSI/AISC 360-16 published by the American Institute of Steel Structures (AISC) The results of the analysis are then adjusted on the section to make the section most economical This study concludes with several examples and discussions of the design of steel structures Note that the computer programs developed by the research team of Shen-Haw Ju are open source and free to use
