摘要
某医院住院部为3层砖混结构,建于1976年,乙类建筑。由于地基浸水不均匀下沉,上部墙体开裂,且原结构抗震构造措施设置不到位,抗震性能低。针对建筑物的现状,采用静压桩、增设混凝土构造柱、圈梁等措施,稳定结构基础,并加强对上部结构的约束,使建筑整体性、抗震性显著提高,取得良好的抗震加固效果,保证在后续使用年限20年内结构的安全使用。
The in-patient building of a hospital is a structure with three layers of brick and concrete, built in 1976, class B building. There are cracks on the upper wall by the uneven subsidence due to foundation flooding, and the seismic design of the original structure was not fully realized, the seismic capacity is low. According to the status of the building the static pressing pile was used, concrete structural columns and beam were added to stabilize the foundation of structure, and strengthen the constraints of the upper structure, so as to raise its integrity and seismic ability obviously, and a good seismic reinforcement effect was got to guarantee the safe use of the structure within its follow-up life of 20 years.
