五层多层接待中心-土木毕业设计汇.docVIP

合肥学院花长城毕业设计 摘 要 本工程为合肥市一处拟建多层接待中心。按使用功能将建筑分为五层的接待中心主楼和局部二层裙房。主楼标高20.7m，局部裙楼两层8.4m。总建筑面积5757.84m2。本建筑物防火等级二级，抗震设防烈度7度。 本工程结构设计采用框架结构，结构计算按横向框架承重分析。内力计算考虑以下三种荷载作用，即水平地震荷载作用下的内力，竖向荷载作用下的内力及重力荷载代表值值作用下的内力。在进行截面抗震设计时，柱按偏压构件计算，为保证延性框架要“强剪弱弯，强柱弱梁，强节点弱构件强锚固的设计原则，且满足构造要求。 关键词： 框架；结构设计；抗震设计 ABSTRACT This engineering is a reception centre of building intending to set up in hefei City. According to the use function, the construct contents five layer’s tall building and two layer’s short building. The high is20.7 ms of Main floor and the partial floor elevation is 8.4 m. Total building area is 5757.84 m2. This building resistant fires is second class, and the anti-seismic garrison is seven degree. This engineering construction design adoption the frame construction, Being calculating the structure, the lateral structure be lacked as frame system and be analysis. construction calculation consider of the action come from three loads, they are horizontal earthquake load, design value of gravity load and representative value of gravity load, we look the column as stubbornly pressed member to compute. In the intrest of the assurance of the frame-work ability continue, we adhere to the design principle is “stranger column and weaker beam, stranger shear force and weaker bending, stranger joint stronger anchorage”. And the cross-section must to meet the demand of construction.
