中文摘要：

为研究带缝RC框架结构的抗震性能，以抗震设防烈度8度区（加速度0．2g）为例，利用OpenSees程序对三种不同高宽比RC框架结构分别建立整浇模型和带缝模型进行了非线性动力反应分析．结果表明，施工缝对框架结构抗震性能的影响与结构或构件进入非线性的程度有关．小震下，结构处于弹性受力状态，施工缝的影响可忽略；中震和大震下，结构进入非线性，施工缝的影响开始凸显，主要表现在使结构的顶点位移增大、层间位移角增大、层间位移角位移分布形式发生改变、关键构件的局部反应加重等．而且，结构进入非线性的程度越深，施工缝的影响作用越明显．有必要从抗震设计角度考虑施工缝的影响．基于现有的两阶段设计方法，从概念设计和计算分析两方面提出抗震设计建议．

英文摘要：

Three different height-width ratio RC frame structures located in intensity region 8 （0.2g） were designed and analyzed using monolithic model and joint model by OpenSees program. The results show that the degree of influence of joint on seismic performance of frame structure and the structure of component into the nonlinear construction related. Under small earthquakes, the structure is in elastic state, and the influence of construction joints can be neglected. In the moderate and strong earthquakes, the structure is in a nonlinear stress state. Influence of construction joints began to highlight, and are mainly shown in the increase of top displacement structure, of inter story displacement angle and the changes of the interlayer displacement angle displacement distribution of bottom displacement form aggravation of and the key components local reactions aggravate. It is necessary to consider the influence of construction joints from the seismic design. Based on the existing two stage design method, seismic design recommendations were proposed from concept design and calculation method.
