围护墙多功能减震结构是一种新型减震结构,其中围护墙与主体结构之间的脆性抗压件是保证该结构形式在小震作用下二者共同工作抵抗地震作用,而在中、大震作用下发挥TMD功效的关键构件。以脆性抗压件的有效厚度和混凝土强度作为主要影响因素,进行10组该连接件的抗压承载力试验,对脆性抗压件的试验结果进行分析,根据混凝土受冲切计算方法提出了该构件的承载力计算方法,为该结构形式的进一步研究提供基础。
Multi-functional vibration-absorption enclosure walls structure is a new type of vibration structure. Brittleness compression elements between frames and enclosure walls are a critical member for the structure. This type of structure ensures that frames and enclosure walls mutually resist earthquake as integral structure under minor earthquakes and as TMD structure under moderate and major earthquake earthquakes. In the test, ten groups of concrete brittleness compression elements with different effective thickness and different concrete intensity were made and the compressing bearing forces of different disks were tested. The results of the experiment were analyzed. Then the calculating formula of brittleness compression element was obtained. Results of the theory analysis and comparing experience showed that the calculation formula obtained by the paper was appliable to analyzing brittleness compression element,and the calculation result was very exact. The result will offer the basis for subsequent experiments.
