1、第五届全国大学生结构设计竞赛带屋顶水箱的竹质多层房屋结构设计计算书作品名称：别具一阁参赛单位：湖南大学参赛队伍：登高自卑参赛队员：张超、卢祖梁、萧文浩指导老师：涂文戈第五届全国大学生结构设计竞赛委员会二○一一年第五届全国大学生结构设计大赛摘要本文从对第五届全国大学生结构设计竞赛的赛题要求的分析入手，明确了以竞赛规定的效率比最大这一设计目标。通过结构选型、荷载分析、构件设计和试验验证等步骤，确立了柔性体系—别具一阁。在结构选型方面，本文借鉴了反应谱理论，通过效率比分析，明确了柔性体系为最佳选择。本文认真考察了竞赛提供材料—本色侧压双色复压竹皮的材

2、料力学性能，为了获取最大的效率比，对框架结构进行了改进以增加其自振周期。本文参考高层钢结构设计理论，对结构构件进行了设计。为了发挥材料力学性能，本文选择了薄壁杆件为主要受力构件，参考了结构稳定性理论，认真考察了构件截面的宽厚比。在荷载效应分析方面，本文立足于抗震规范，通过振型分解反应谱法对结构进行抗震设计，通过大型通用有限元软件ANSYS利用时程分析法对模型进行位移和应力进行校核。另外，本文还对赛题提供的屋顶水箱（TLD）进行了频域分析，结合我们的结构形式，为了获取最大的荷载布置，最终选择水箱注满水。最后，本文通过竞赛规定的试验步骤及试验条件对
