某六层砖混结构民用住宅楼毕业设计(PKPM软件)
| 摘要: 本工程为多层砖混民用住宅。建筑层数为六层、建筑高度为20.38m，基底占地面积为574.33㎡、总建筑面积3470.0㎡。抗震设防烈度7度、场地类别为Ⅱ类，结构设计使用年限为50年。本工程为二类建筑，耐火等级为二级，工程±0.00同绝对标高13.38m。 结构设计依据国家相关规范进行：计算各楼板和屋面板的恒荷载，同时确定活载值。根据荷载设计值计算出楼面和屋面的配筋。将板上均布荷载传给各墙,然后根据各墙所受荷载及墙体自重，验算墙体抗压承载力。根据抗震设防数据及结构重力荷载代表值，计算出水平地震作用下的各墙承担的剪力，并验算墙体的抗剪承载力。计算出各段基础上部荷载，并由此确定基础类型和配筋。 设计中使用了中国建筑科学研究院编制的PKPM软件。 经过验算，该结构符合安全性、可靠性要求。 [关键词]:砖混结构、承载力，软件 The design of multistory brick and concrete mixed building Abstract: This engineering is a multistory building. It is a brick and concrete mixed structure. The building has six tiers,building height is 20.38m. Gross building area is 574.33m²,total floor space is 3470.0m². Intensity of anti-seismic de- -fence is establishe to 7 degree. The fields classification isⅡ.The structure is designed to use 50 years.The engineering is the second type building,its refractory ranks the second grade.The engineerings designed elevation is equal to 13.38 of absolute elevation . Structural design accords to the national special codes: first of all,we calcu- -late each floor and roofs dead live of slab,and carry live load at same time. According to computation of design load,we can design the concrete reinforcement of floor and roof. Transfer the uniform loading to each wall,than according to the load that wall suffer and self-weight ,we can check the walls compressive bearing capacity.According to the data of anti-seismic defence and structural representative value of gravity load ,each walls shear force can be worked out,than we can check the walls shear bearing capacity.Compute the load that base bear, than according to computation ,we can fix the base form and calculate the concrete reinforcement. The PKPM software which is made by China Academy Of Building Research was used in the course of design. This structure accords with the safety and reliablity request by checking.
