蜂窝式钢框架结构设计方法研究 摘 要： 蜂窝式钢框架结构是一种将蜂窝梁与实腹柱或蜂窝柱通过焊接或螺栓连接而成的新型钢框架结构体系。不但具有传统钢框架结构的技术优势，而且可以充分利用蜂窝梁节省钢材，自重Abstract Cellular steel frame structure is a new steel frame structure which makes the cellular beam and solid web or cell column connected by welding or bolting. It not only has technical advantages of the traditional steel frame structure, but also can take full use of the cellular beams to save steel and reduce weight etc. Selection of cellular steel frame structure, can reduce the use of columns and maintenance materials. Pipeline going through the cellular holes, can reduce the building storey. Visible, applied it in high-rise buildings, can obtain better economic and social benefits. As a special production process, in the same flexural capacity, the cellular beam weight lighter than ordinary solid web beams, which can further reduce the seismic response. Now, the main fator of restricting cellular steel frame structure development and application is the regularity affect of cellular beam hole parameters (including the hole size and hole location, etc). on the overall seismic performance of cellular steel frame is unclear. So far, domestic and foreign researchers most are concentrated on the cellular beams, columns and other individual components, but research on the overall cellular framework for seismic design is little, and systematic cellular steel frame design methods hasnt formed. In this paper, on the basis of steel frame structure in the cellular quasi-static test，the finite element analysis was used to do simulation analysis. And use the finite element method to anysis seismic performance of different hole shapes, expansion ratio, hole location of cellular steel frame structure under the effect of cyclic loading effects in the cyclic loading, and matain the cellular beam hole location, the expansion ratio recommended value formula. Specific research content and conclusions are as follows: Simulation analysis on different expansion ratio and beam hole l
