项目摘要
This project is concerned with three related issues affecting the seismic structures, particularly steel structures. The first one is the incremental collapse issue, which may arise when a structure has inadequate strength and inelastic stiffness to prevent continuous drifting of the structure due to P-delta effects. The second issue is the column strength requirements under gravity plus seismic design loads, considering the interaction between axial loads and bending moments. The third issue is column buckling under overloads during earthquakes. The objective of the research is to investigate these problems and to develop feasible solutions. Parameter studies through computer simulation will be performed to account for the effects of the geometric and material nonlinearities involved research. The results of the study will be presented in the form of design recommendations that can be readily implemented in engineering practice. The study will improve the current code design or seismic stability of steel frames.
本项目涉及影响抗震结构,特别是钢结构的三个相关问题。第一个是增量崩溃问题,当结构的强度和非弹性刚度不足以防止结构由于P-delta效应而持续漂移时,可能会出现增量崩溃问题。第二个问题是考虑轴向载荷和弯矩之间的相互作用,在重力加地震设计荷载下的柱强度要求。第三个问题是地震荷载作用下柱的屈曲。研究的目的是调查这些问题,并制定可行的解决方案。通过计算机模拟进行参数研究,以解释所涉及的几何和材料非线性的影响。研究结果将以设计建议的形式呈现,这些建议可以很容易地在工程实践中实施。该研究将改进现行钢框架抗震稳定性设计规范。
