屈服钢板墙耗能机理研究
|
摘要
在抗震设防区,特别是在高烈度区的建筑结构中,地震作用是影响结构安全性的主要因素。通过合理的结构设计,使结构整体在小震作用时,能够满足一定的承载力和刚度要求,并且在中震、大震作用下,具备足够的耗能能力和延性,是对建筑物抗侧力体系提出的基本要求。
根据实际工程需要,参考已有钢板剪力墙、金属屈服耗能器以及极低屈服点钢材的研究结果,本文提出了一种核心部件由低强度、高塑性退火热处理钢板组成的新型屈服钢板墙。
通过钢板退火热处理试验,确定了最佳退火温度为850℃;经退火热处理,钢板屈服强度降低到Q195水平,塑性性能也有较大改善。
完成了不同加劲肋加设方式、不同试件连接方式的11个足尺试件的低周往复拟静力试验,并根据试验结果分别从滞回性能、耗能性能、延性性能等方面进行了分析。结果表明,新型屈服钢板墙具有初始刚度较大,承载力较高,耗能性能较强等特点;屈服钢板墙约束板端部先焊接厚钢板,再用高强螺栓连接的方式较为合理可靠;加劲肋加设方式对试件滞回性能、耗能性能、承载力及刚度有较大影响;中间加劲肋可以有效地提高试件的耗能性能、承载力及延性性能;两侧加劲肋可以有效地提高试件的承载力,并对试件耗能性能有影响。
在试验过程中,根据试验结果对屈服钢板墙的构造形式进行了多次改进,最终确定了一种较为理想的屈服钢板墙的构造形式,并对该结构在实际中的应用提出了建议。
In earthquake-resistance protection zone, especially the buildings in high earthquake intensity regions, earthquake's action has been the main factor of structure's safety. It is important to design reasonable structures to meet the needs of supporting capacity and rigidity under small earthquakes, and energy-dissipation capacity and ductility under moderate, strong earthquakes. These bring high requirement to lateral resisting system.
According to the actual engineering demand, referring to the research findings of steel plate shear wall, metallic yield dampers and ultra low yield point steel, a new kind of steel plate shear wall with core part composed of annealed steel plate, which has the low-intensity, high-ductility nature, is presented in this paper.
Through annealing experiment of steel plate, 850℃is considered as the best annealing temperature. After annealing heat treatment, the yield strength of the steel plate reduces to the level of Q195 and the plastic performance has greatly been improved.
Eleven full scale specimens with the different stiffening ribs and connection mode are tested under the cyclic lateral loads in a quasi-static condition. Based on the test data, properties of the new kind of steel plate shear wall, such as hysteretic performance,energy dissipation property,capacity of ductility are analyzed in the paper. The result indicated as follows: The new kind of steel plate shear wall has the better properties, such as bigger initial rigidity, higher supporting capacity and stronger energy-dissipation capacity; The connection mode that the end of steel plate shear wall is firstly welded onto a piece of steel plate, then connected by high-strength bolt is reasonable and reliable; The way of stiffening ribs' setting has a great influence on the steel plate shear wall's hysteretic performance,energy dissipation property , supporting capacity and rigidity. The middle stiffening rib could effectively improve specimens' energy dissipation property, supporting capacity and capacity of ductility; Both sides stiffening rib could effectively improve specimens' supporting capacity and has a influence on energy dissipation property.
In the course of the experiment, according to test results, a number of improvements of the steel plate shear wall's structural style are done. A more desirable structural style are determined, and the recommendations of its application in the actual use are given.
