摘要

单跨框架结构是种严重抗震不利体系,缺乏冗余约束,易发生整体倒塌,在抗震设防要求提高情况下,需要进行加固。翼墙加固因布置方便、概念明确而得到广大推崇,但对其加固效果到底如何并不清楚。本文通过对一栋典型中学教学楼进行翼墙加固分析,探讨了各种翼墙尺寸及类型对加固效果的影响,提出翼墙加固时应注意的问题及建议。
With lack of redundant constraints,single-span frame structure is a weak seismic system and easy to collapse.Since the seismic fortification was enhanced,the existing buildings need to be strengthened to improve seismic performance.Wing-wall strengthening has been well concerned for its convenient layout and good bearing capacity,but it is unclear how this method would be effective.In this paper,the seismic performance of a typical school building strengthened by wing-walls is analyzed,and the strengthening effect under various sizes and types of wing-wall is discussed in details.Some questions and suggestions in wing-wall strengthening engineering are also proposed.
