6层框架公寓楼结构设计计算书

摘要该建筑物是榆林学院 17#公寓楼。根据提供的地形图和及功能要求的规定，进行建筑设计。它的占地面积约 835㎡，建筑面积约 5007 ㎡。建筑物最高高度为 21m。此建筑物采纳钢筋混凝土框架结构，结构设计是六度设防，设计地震是第一组，场地为Ⅱ类，粗糙度为 B 类。其设计内容包括结构布置、构件估算、内力分析、构件截面设计和基础设计几部分。采纳整体现浇式，建筑整体刚度较好并进行了进行了地震作用、风荷载和竖向荷载的内力分析，采纳了多种荷载组合方式。钢筋混凝土是一种延性材料，为了充分利用这种材料的特性，根据建筑三级抗震的要求，进行梁端弯矩调幅，柱端弯矩调整，剪力调整等计算，同时注意节点的设计，使得建筑的设计达到强柱弱梁，强剪弱弯的要求，增加建筑的延性，以提高建筑的使用性能。在此次设计中，多层框架结构分析是采纳底部剪力法进行地震荷载下的内力分析；采纳弯矩二次分配法进行竖向荷载的内力分析，整个结构的设计均依据法律规范来计算。关键词： 框架; 荷载; 抗震; 钢筋混凝土AbstractThis building is located Yulin a multilayered frame student apartment of 17#. According to topographic diagram which provides and function request stipulation, carries on the architectural design. Its area approximately 835m2, floor space approximately 5,007 m2. Building high is 21m。This building uses the reinforced concrete portal frame construction, the structural design is six garrisons, the design earthquake is the first group, the location is II kind, roughness is B kind. Its design content including the structural arrangement, the component estimate, the plane unit choice, the endogenic force analysis, the component section design and the foundation designs several parts. Used placement ,the construction overall rigidity is better and carries on has carried on the earthquake load, the wind load and the vertical load endogenic force analysis, has selected the many kinds of loads combination method。The reinforced concrete is one kind of ductility material, in order to fu...
