摘  要：本工程建造地点在浙江杭州，建筑层数六层。结构形式是现浇钢筋混凝土框架结构；基础采用伐板基础；建筑结构安全等级二级，设计使用年限为50年。非抗震;基本风压为0.4KN/㎡。室内设计标高为±0.000，室内外高差400mm。
 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。内力计算考虑以下四种荷载作用，即水平地震荷载作用下的内力，竖向恒载作用下的内力，重力荷载设计值作用下的内力及风载作用下的内力，。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。
 主体结构中，先进行框架结构设计计算，再进行楼梯，板和其它构件计算
.最后进行了基础设计。

Abstract: The location of this engineering is Hangzhou ,  Zhejiang province. The building counts six layers. The construction form is cast-in-situ reinforced concrete frame; the seismic fortification intensity is lower than six degree; the reference wind pressure is 1.2 KN/㎡.The interior elevation is±0.000,and it is 400mm higher than outdoor.
 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 four loads, they are horizontal earthquake load, design value of gravity load and representative value of gravity load, and the other is wind load. Being underway the design of cross-section anti-seismic, 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.
 The main structure, carry out a framework of structural design, to conduct the stairs, boards and other components calculated. Finally, the foundation design.

Keywords: cast-in-situ concrete    frame    design
