摘要:

为研究宽柱双梁框架结构体系在地震作用下的受力机理、破坏特征及整体抗震性能,采用微粒混凝土、镀锌铁丝、黏土砖等材料制作了缩尺比例为1:4的三层宽柱双梁框架结构体系模型,分别进行了X向、Y向水平地震作用下的振动台试验,得到了模型结构在不同工况地震作用下的破坏形式、破坏过程及动力特性等。结果表明:该结构在输入峰值加速度0.055g(g为重力加速度)及0.15g地震作用下基本处于完好状态,在0.31g地震作用下发生轻微破坏,经历多次0.4g地震作用后,模型结构发生严重破坏而未倒塌,且仍保持一定的承载能力; 结构最严重的破坏部位发生在外贴墙纵横向相交的墙角处,但外贴墙与框架仍保持较好连接,结构体系合理可靠,具有足够的抗侧刚度和良好的抗震性能,可达到7度区“小震不坏,中震可修,大震不倒”的设防目标。

Abstract:

In order to study the force mechanism, damage characteristics and overall seismic performance of the wide-column double-beam frame structural system under seismic action, a three-story wide-column double-beam frame structural system model with a scaled-down ratio of 1:4 was fabricated using particulate concrete, galvanized iron wire, clay bricks and other materials. A vibration table test study was carried out under X- and Y-direction horizontal earthquakes, the damage forms, damage processes and dynamic characteristics of the model structure were obtained under different working conditions of earthquakes. The results show that the structure is basically in a good state under the peak ground acceleration of 0.055g(g is gravity acceleration)and 0.15g earthquake actions, with minor damage occurring under the peak ground acceleration of 0.31g. After experiencing multiple earthquake actions of 0.4g, the model structure suffers severe damage but dose not collapse, and still maintains a certain level of bearing capacity. The most serious damage to the structure occurs at the corner where the external wall intersects vertically and horizontally, but the external wall and the frame are still well connected. The structural system is reasonable and reliable, possessing sufficient lateral stiffness and excellent seismic performance, and can meet the fortification targets of “undamaged under minor earthquakes, repairable under moderate earthquakes, and not collapsing under major earthquakes” in the 7th seismic intensity region.
