Research On Earthquake-Resistant Capacity Of Multi-Storey Steel Structure House

Steel sturcture house, which have perfect earthquake-resistant capacity, good material strength and ductility, convenient construction and recovery, high space utilization ratio,efficient in saving land and energy, reducing comsuption, will be a very good choice in housing industrialization development. Now, China has the most steel production, and maturity technology in steel structure production, designing and installation. So, steel house industrialization development will be an important aspect of housing industrialization development.This paper focus on the housing steel structure which suitable for housing industrialization development. It simply introduces property of steel structure house, history and development in tadays of China and abroad, especially for the Japanese research and development in this field. It also introduces architecture supporting system and structure system in earthquake-resistant suitable for steel sturcture house. Here we focus on the earthquake-resistant designing method for steel sturcture house. We choose 2 typical building 6 floors and 11 floors and establish three models, which are frame structure, frame brace structure and frame wall structure, on them. The 6 floors building has be searched by using response spectrum analysis of frequently occurred earthquake and pushover analysis of seldom occurred earthquake in 9 degree intensity. The 11 floors building has be searched by using response spectrum analysis of frequently occurred earthquake and pushover analysis of seldom occurred earthquake in 8 degree intensity. Comparation the model analysis, column shear, floor Centroid displacement, story drift and angles of drift in frequently occurred earthquake, hinge property in PUSHOVER analysis and capacity point in seldom occurred earthquake, we have briefly known the structure property, force information, sidesway, energy dissipation, the begin and development of hinge in each structure. We clear how to design and solve the problem occurred. And we also take some advice to the advanced research.
