摘要

提高结构的侧向刚度和耗能能力是提高结构抗震性能的有效途径。支撑体系是框架结构抗震设计中最有效、最可靠的解决方案之一。本文详细介绍了采用基于位移的设计方法对支撑系统进行设计的步骤。以地震地震动作用下的钢支撑框架结构为例,对该方法的有效性进行了评价。计算结果表明,支撑具有较好的降低建筑结构水平位移和剪力的效果。

Increasing lateral stiffness and energy dissipation capacity is considered an effective solution to improve the seismic performance of building structures. The bracing system is one of the most effective and reliable solutions in seismic-resistant design for frame structures. In this study, the step-by-step of design for a bracing system according to the displacement-based design method is detailed. A typical study is performed on a steel-braced frame structure, subjected to earthquake ground motion to evaluate the effectiveness of the solution. The obtained results show that the bracing has good effects in reducing the horizontal displacement and shear force for building structures.
