高层剪力墙结构结构试验,主要研究在静载作用下的小偏心受压及大偏心受压的强度、抗剪强度、抗裂性、横向钢筋的构造配筋率,并探讨在反复荷载作用下的受力性能。为此,要求测量出剪力墙在破坏前的荷载、应变、位移关系曲线,在破坏阶段中的极限延伸性能等。试验中荷载测量精度不低于满量程的1%,挠度、极限延伸性和支座沉陷的位移测量精度±0.01～±0.02毫米。弹性范围内的应变测量精度±1～±2με,其他为±3με～±5με。剪力墙试件高4.9米、宽2.3米(个别1.2米)、厚0.1～0.2米
The high-rise shear wall structure test mainly studies the strength, shear strength, crack resistance, and structural reinforcement ratio of small eccentric compression and large eccentric compression under static load, and discusses the effect of repeated loading. Under the force performance. For this purpose, it is required to measure the load-strain, displacement-displacement curve of the shear wall before failure, and the ultimate elongation performance in the failure phase. The accuracy of the load measurement during the test is not less than 1% of the full scale, and the deflection, limit extensibility, and the displacement measurement accuracy of the support subsidence are ±0.01 to ±0.02 mm. The strain measurement accuracy within the elastic range is ±1 to ±2με, and the other is ±3με to ±5με. Shear wall specimen height 4.9 meters, width 2.3 meters (individual 1.2 meters), thickness 0.1 to 0.2 meters
