某超限底框砌体结构抗震加固设计

Seismic Reinforcement Design for Masonry Frame Structurebeyond Code Limits

对于平面规则的超限底框砌体建筑,该文提出改变结构体系加固法,通过在局部墙体增设钢筋网片混凝土面层,局部设置混凝土剪力墙和框架柱,部分墙体在楼层处增设钢拉梁,形成广义框架-核心筒结构,不仅满足抗震要求,而且最大限度减少入户施工。该方法可为同类工程提供借鉴和参考。

For the masonry frame structure beyond code limits, this paper presents reinforcement method to alter structural system. By adding steel bar network-concrete surface into local wall, concrete shear wall and frame columns locally, and steel tie beams into wall layers to form frame-core tube, not only meeting seismic requirements, but reducing into-room construction to the maximum extent. It can offer some references for similar projects.
