本文对10度区某砖混结构医院分别进行了水平地震荷载单独作用和水平与竖向地震荷载组合作用下的抗震验算.通过分析和比较表明,在10度区,建筑物所受到的竖向地震作用不容忽视.在竖向地震作用下,各层砖砌体的抗剪能力削弱,顶层墙体往往出现拉应力,建筑物可能遭受严重破坏,甚至倒塌,在抗震设计和加固中,应予以充分注意.
In this paper, the earthquake-resistance calculation under the combined effect of horizontal seismic load and horizontal and vertical seismic loads is separately performed for a brick-concrete structure hospital in the 10th district. Through analysis and comparison, the vertical direction of the building is shown in the 10 degree zone. Earthquake action can not be ignored. Under the effect of vertical earthquake, the shear resistance of each layer of brick masonry is weakened, the top wall often appears tensile stress, the building may be severely damaged, or even collapsed, should be given in seismic design and reinforcement. Full attention.
