ABSTRACT

The hybrid steel frame is a new laterally resistant steel frame composed of rigid and semi-rigid connections. The objective of this study is to select a hybrid frame with an appropriate seismic performance based on a multi-criteria decision-making approach. The seismic performance of different patterns and positions of semi-rigid connections within the selected frames is examined. Static, cyclic and nonlinear dynamic analyses are conducted on the selected frames. The Analytic Hierarchy Process is then used to evaluate the performance of the frames. The results indicate that the hybrid frame can offer an enhanced performance in comparison with rigid frames if the hybrid frame is well proportioned.

摘要

混合钢架是一种由刚性和半刚性连接组成的新型抗横向钢架。本研究的目的是基于多准则决策方法选择具有适当抗震性能的混合框架。检查了所选框架内半刚性连接的不同模式和位置​​的抗震性能。对选定的框架进行静态、循环和非线性动态分析。然后使用层次分析过程来评估框架的性能。结果表明，如果混合框架比例合理，则与刚性框架相比，混合框架可以提供增强的性能。
