【摘要】 外廊式单跨框架教学楼是现有中小学教学楼结构中常见的结构体系,抗震加固时,由于乙类建筑不应采用单跨框架,从施工工期和技术经济角度分析,采用在挑梁端部设柱方式改单跨框架为双跨框架的加固方法,是一种简单有效地加固方法。本文采用静力弹塑性法及按实配钢筋同时考虑楼板T形截面影响的弹塑性动力时程分析法,对该类加固方法进行研究,其研究成果可供中小学教学楼抗震加固设计时参考。

【Abstract】 Exterior corridor type single span framework buildings are very popular structure system in school buildings of middle and primary schools.Because the structure of single span framework should not be used in the building of B-class(important building),from the viewpoint of construction time and convenience of technique,in seismic-proof strengthening,it is a simple and effective method by changing structure to double span framework.In this paper this effective method is researched by elasto-plastic dynamic analysis of structure based on reinforcing bar of actual amount and meanwhile considering influence of the effective width of T-section of floor.Our result can be referenced in design of aseismatic strengthening for the buildings of middle and primary schools.
