一、前言在地震区,多层砌筑房屋采用了配筋构造,使得该类房屋具有一定的塑性变形能力。许多震害表明,无筋砌体房屋往往由于变形集中在个别层而引起整幢房屋倒塌。本文试图寻求这种变形分布不均匀的规律,提出改善方法,以避免具有有限变形能力的配筋砌体房屋发生类似破坏。 I. INTRODUCTION In the earthquake area, multi-layered masonry houses have been equipped with reinforced structures, making this kind of house a certain degree of plastic deformation. Many earthquake damages have shown that unreinforced masonry houses often collapse due to deformation concentrated in individual layers. This paper attempts to seek the law of uneven distribution of deformation and proposes an improvement method to avoid similar damages of reinforced masonry houses with limited deformability.
