With the socio-economic development, good, rich architectural artistic expression, steel structure generally favored by architects in traditional metallurgical industrial plant, the construction of high-rise and high-rise and large span structures for many years in practice, so that the steel structure of the outstanding advantages role almost irreplaceable. In recent years, the steel structure in the country is the development of unconventional, more extensive application, the impact of rapid expansion. The multi-storey steel structure residential system has a number of advantages seismic performance, speed of construction, the basis for a relatively low cost, light weight, quick and easy on-site installation, can be industrial production, green. These advantages are completely in line with the trend of China’s housing industry, and get better and better development in the construction industry in China and attention.This paper studies the multi-layer light steel structure of the residential system selection, layout program, to optimize the design in practical engineering application of the cost-effectiveness analysis and evaluation, the paper selects five-layer the pure steel framework model, II class venue, earthquake grouping for the first the two groups,9Area SAP2000finite element software to simulate the structure under rare earthquake static nonlinear seismic analysis, to understand the plastic hinge development; This article lists the five-story light steel residential and five-story masonry structure housing Benefit contrast, come to the main steel structure material is higher than the main material cost of the brickwork, light steel base cost is low compared with the brickwork wall of light steel residential construction cost is high compared to the masonry structure, doors, windows and utilities both cost basically the same, to put forward the views and recommendations of the popularization and application of for the multilayer light steel residential applications, also play a role in guiding engineering design. |
