为了推广应用预制轻质混凝土承重墙,本文以一幢2层预制混凝土结构实际工程为背景,通过足尺预制轻质混凝土承重墙开展了单调静力荷载试验,对墙体裂缝分布、破坏形态等进行了较系统的研究。试验结果表明预制轻质混凝土墙的破坏主要集中于墙体与地梁之间的连接处,墙体自身的破坏并不显著;最终破坏时,墙内纵向钢筋未屈服,表明应该加强预制墙体与地梁之间的连接。
In order to promote the application of precast lightweight concrete load-bearing walls, this paper takes a 2-story prefabricated concrete structure as the background and carries out monotonic static load tests on full-scale precast lightweight concrete load-bearing walls. The crack distribution, Conducted a more systematic study. The test results show that the damage of prefabricated lightweight concrete walls mainly concentrates on the connection between the wall and the ground beam, and the failure of the wall itself is not significant. When the final failure occurs, the longitudinal reinforcement in the wall does not yield, indicating that the prefabricated wall should be strengthened The connection to the ground beam.
