基于位移的抗震设计中位移模式的确定
|
摘要
根据地震强度、地震波、结构层数与跨度、强柱弱梁系数等影响水平位移模式的主要因素,通过大量算例分析,提出了确定基于位移的抗震设计中水平位移模式的方法.
Nonlinear static analysis and equivalent single degree freedom methods are primarily applied in displacement-based seismic design and the definition of displacement-mode is essential step of the methods. Based on displacement-mode effect factors such as earthquake intensity, earthquake waves, structure height and span and strong column-weak beam coefficients etc, this paper proposes the definition method of displacement-mode in displacement-based seismic design by a great number calculations.
