摘要
首先对砖混结构的震害进行分析,使砌体结构在强烈地震作用下发生破坏的外因是地震动,内因是结构特性.提出多层砖混结构抗震构造措施,规范规定的构造措施都是为了保证房屋的整体性,增大延性.在多层砌体房屋抗震验算中,指出多层砖混结构抗震验算的实质是对墙体的水平抗剪强度进行复核.并探讨了建筑物采取的抗震措施,包括建筑结构的隔震减震、施工质量以及目前多层砖房施工中存在的问题。
In this paper,the earthquake damage of brick-and-concrete composite construction is analysed at first.The external reason that causes masonary structare to collapse is earthquake vibration.The intermal reason that produces seismic action and cause masonary structure to sustain damage is the specific propery of structure.The above two factors cause masonary structure to collapse under the intense seismic action.Then,the constructional measures of multi-story brick-and-concrete composite structure are discussed.The antiseismic measures specified in the codeall are to ensure the integrity of houses and to increase the ductility.In the antiseismic checking computation of multi-story masonary houses,the view is given that is the substence of the anti-seismic checking computation of multi-story masonary houses is to check the horizontal shearing strength of the wall.At last,the problem of anti-seismic measures of building is discussed.It includes the earthquake isolation and dampening of building structure and construction quality,and the problems that lie in the construction of multi-story masonary houses.The problems discussed in this paper have an important sense to the anti-seismic design of multi-story masonary houses.
