In order to study the feasibility of different types cross section columns combination of multi-layer steel frames optimum design, considering the basic cycle, the first layer shear-weight ratio, steel weight of structure and other factors to establish different types of models. Through the each model fees of different engineering cost quota, then from cost of the project perspective to analyze the optimum design of multi-layer steel frames. The analysis results: Two kinds of calculations of the project cost of each model’s main structure are different, the project cost quota of Guangxi mainly depends on steel weight of each component type, but the project cost quota of Osaka region general considering the component types and cost of material and processing fees which are determined by section types, and welding quantity is single calculated, model CM4 corresponds well. On the whole, model CM4 has the lower expenses. So Guangxi district should refining component types and section types and then determine production and installation fees. |
