【摘要】 通过 5个砖混改造工程中常用的混凝土梁柱换墙技术的试件试验,了解了其受力特征、破坏形态。试验研究证明,只要后置墙梁与上部墙体间采取适当的连接构造措施,两者便可协同工作,这时其与普通墙梁具有相似的工作机理。因此,可采用普通墙梁设计方法进行设计,但应适当提高其安全度。更多还原

【Abstract】 The stress and modes of failure of postpositioned wall beam were studied through five projects,in which the masonry wall was replaced by concrete beams in rebuilding.Experimental research proved that beam can cooperate with upside if they have reliable joint,which means the structure has the same behavior with beam wall.This paper treats this structure postpositioned wall beam.It can be designed as wall beam,but the safety grade should be increased.更多还原
