[摘要] 為了推廣應用預制輕質混凝土承重墻，本文以一幢2層預制混凝土結構實際工程為背景，通過足尺預制輕質混凝土承重墻開展了單調靜力荷載試驗，對墻體裂縫分布、破壞形態(tài)等進行了較系統(tǒng)的研究。試驗結果表明預制輕質混凝土墻的破壞主要集中于墻體與地梁之間的連接處，墻體自身的破壞并不顯著；最終破壞時，墻內縱向鋼筋未屈服，表明應該加強預制墻體與地梁之間的連接。

Abstract: In order to promote the use of precast lightweight concrete load-bearing walls, a full-scale precast lightweight concrete load-bearing wall, which was designed according to a two story prototype residential building, was tested under monotonic loading. Behavior of the test specimen was evaluated in terms of distribution of cracks, failure mode, etc. Test results showed that the damage of the test specimen was mainly distributed around the connection between the precast lightweight concrete wall and the ground beam, and the destruction of the wall itself was not significant; the tensile longitudinal reinforcements did not yield, which showed that the connection between the precast wall and the ground beam should be further strengthened.
Keywords: precast; lightweight concrete; wall; failure mode
