摘  要： 本设计是商住桁架工程结构设计，位于浙江。商业部分4544.7㎡，住宅部分4055.7 ㎡，底层占地面积约为785㎡，总高为19.6m，属多层建筑。地震设防烈度为六度，抗震等级为四级；建筑结构安全等级二级，设计使用年限为50年，设计中不考虑抗震计算。本方案采用钢筋混凝土现浇桁架结构，主体结构为双向承重桁架。在进行荷载计算和构件截面估算后，选取一榀桁架进行计算，用分层法算出内力，并对最不利荷载组合进行分析，通过D值法求出风荷载，进而进行桁架梁柱截面设计。并选取部分楼面板、楼梯、独立基础、地梁进行设计。本方案基础形式采用独立基础，楼梯为钢筋混凝土现浇板式楼梯。整个方案设计基本符合设计和结构要求

 A six-story commercial framework for project design 4
Abstract: This design is the business-living building, located in Zhejiang. The business construction area of about 4544.7㎡, the living construction area of about 4055.7㎡and bottom covers about 785㎡, the total high is 19.6 m, is a multi-storey building. The earthquake intensity is six degrees to setup defences, the forth grade antidetonation, Structural safety grade two and the design life span of 50 years. The Design did not consider seismic calculations. The program used cast-in-place reinforced concrete frame structure, the main load-bearing structure of the two-way framework. Conducting load calculation and after estimating beam, select a framework for load calculations, using layered calculated forces, later analysis the most unfavorable load portfolio ,through D value derived wind load, and then cross-section beams framework for the design. And select some floor panels, staircases, the independent foundation and footing beam design. This basic form is pile, the stair is the stair of cast-in-place modes in Chinese operatic music of armored concrete . The whole conceptual design accords with the design
