通过对六片不同高厚比和偏心距的夹心墙,进行竖向荷载作用下的静力试验研究,得到新型横孔空心砌块砌体在竖向荷载作用下的破坏形态、横竖向变形规律、开裂荷载、破坏荷载及裂缝发展情况等。基于试验结果并参考现行国家规范,提出了这种新型横孔空心砌块砌体夹心墙受压承载力的计算方法。对比结果表明,试验值与理论分析值吻合较好。本文解决了新型横孔空心砌块砌体夹心墙抗压强度设计问题,为这种砌块夹心墙体的设计和施工提供了重要依据。
Six kinds of sandwich walls with different thick-to-thick ratio and eccentricity were used to study the static behavior under vertical load. The failure modes, transverse and vertical deformation of the new type of horizontal hollow block masonry under vertical load were obtained. , Cracking load, failure load and crack development. Based on the test results and with reference to the existing national codes, the calculation method of compressive bearing capacity of the new type of horizontal hollow masonry sandwich masonry walls with hollow block is put forward. The comparison results show that the experimental value is in good agreement with the theoretical analysis. This paper solves the design problem of the compressive strength of the new horizontal hole hollow block masonry sandwich wall and provides an important basis for the design and construction of such a sandwich wall.
