摘要:

为研究框架-嵌入式墙体结构抗震性能,根据原型结构特性与相似理论,设计并制作了相似比为1:3的钢筋混凝土框架-嵌入式墙体结构试验模型,并进行了地震模拟振动台试验,探究此类结构在不同强度、不同种类地震波作用下的动力特性、加速度反应和位移反应等。结果表明:在地震作用初始阶段,框架结构的变形使得墙板与主体框架连接更为紧密,嵌入式墙体的存在使得整体结构刚度增加,随着框架主体结构的损伤,刚度逐渐减小; 加载结束后,结构一层梁端及柱脚处裂缝较为密集,嵌入式墙板四角及插墙凹槽处混凝土出现不同程度的破坏,框架柱插墙凹槽处混凝土损坏较为严重,但墙柱之间仍保持可靠的连接,结构仍保持较好的整体性; 结构各层弹性、弹塑性层间位移角在规范限值以内,结构具有良好的抗震性能; 振动台试验过程中各块墙板间相对振动反应较为明显,在实际工程设计中应对墙角采取构造措施加固,在墙板顶端增设压梁,并在墙板与框架柱凹槽之间增设缓冲带。

Abstract:

In order to study the seismic performance of frame embedded wall structure, according to the prototype structure characteristics and similarity theory, a reinforced concrete frame embedded wall structure test model with the similarity ratio of 1:3 was designed and made. The shaking table test was carried out to explore the dynamic characteristics, acceleration response and displacement response of this kind of structure under different intensity and different kinds of seismic waves. The results show that in the initial stage of earthquake, the deformation of the frame structure makes the connection between the wall panel and the main frame more closely, the existence of embedded wall makes the overall structure stiffness increase, and with the damage of the main structure of the frame, the stiffness gradually decreases. After the end of loading, the cracks at the beam end and column base of the first floor of the structure are more dense, and the concrete at the four corners of embedded wallboard and the groove of inserted wall are damaged to varying degrees. The damage of concrete in the groove of frame column is serious, but the connection between wall and column is still reliable, and the structure still keeps good integrity. The elastic and elastic-plastic inter story displacement angles of the structure are within the limits of the code, and the structure has good seismic performance. In the process of shaking table test, the relative vibration response of each wallboard is obvious. In the actual engineering design, structural measures should be taken to strengthen the wall corner, adding pressure beam at the top of the wall panel, and adding buffer belt between the wall panel and the frame column groove.
