[提要] 用彈塑性有限元法計(jì)算分析了單層和八層墻片在豎向和水平力作用下彈性階段的應(yīng)力狀態(tài)及其極限抗側(cè)承載力。結(jié)果表明彎矩對墻體抗側(cè)承載力有很大的影響。在不考慮墻體翼緣作用的條件下，八層墻體的抗側(cè)極限力為相應(yīng)單層墻體的44%。

By using of elasto-plastic finite element method the stress state and limit lateral capacity of the masonry wall of single and eight storeys under vertical and horizontal actions were analyszed. The result showed that the bending moment would had great influence on the limit lateral capacity of the masonry wall. If the effection of the flange walls will not be considered the limit lateral capacity of the masonry wall in eight storeys would has only 44% of the one of the corresponding wall in single storey.
Keywords: masonry wall; bending effect; limit lateral capacity
