本文对多层砖房在地震作用下的反应进行了分析,认为水平地震起主要作用;但在8°,9°地震区,竖向地震作用不容忽视;由于竖向地震作用,使水平抗剪强度降低达30％。文中还给出了竖向地震荷载的近似公式。 This article analyzes the response of multi-story brick houses under earthquake action, and considers that horizontal earthquakes play a major role; however, in the 8° and 9° earthquake regions, vertical earthquake action cannot be ignored; horizontal shearing acts due to vertical earthquakes. The intensity is reduced by up to 30%. The approximate formula for vertical seismic load is also given in this paper.
