摘要本工程为某十二层高校科研楼钢框架结构设计，标准层层高为3m，底层层高为4.2m。总高度为37.2m。建筑总面积为16000m2。钢框架结构由于结构钢材延性好，能够很好抵抗地震变形；由于本身重量轻，可以减轻结构竖向自重；施工周期短以及空间布置灵活。本结构设计内容涉及钢框架在地震作用和风荷载作用下的水平侧移验算、强度验算、整体稳定验算以及对结构各个节点的设计。在用底部剪力法求出水平地震作用后，利用D值法完成了水平地震作用下的一榀框架的内力组合计算。采用弯矩分层法分别完成了恒载和活载最不利布置作用下的内力计算。接着进行结构构件的地震作用效应与其它荷载效应的基本组合及无地震作用效应与其它荷载效应的基本组合两种情况，对框架内力进行组合，得出框架梁柱的控制内力。用天正2008、AutoCAD2007、PKPM2008软件等计算并绘制本工程建筑和结构施工图。52546

ABSTRACT  This project for a The twelfth university steel frame structure design, high standard layer upon layer of 3 m, the height is 4.2 m. The total building area of this project is 16000m2. Because of its good ductility of steel structure, steel frame structure can resist earthquake deformation; Because itself is lightweight, can reduce the structure vertical gravity; Short construction period, and flexible space arrangements. This structure design content relates to the steel frame under earthquake and wind load calculation, strength calculation, lateral stability checking calculation and the structure design of each node. After the horizontal earthquake is calculated by the bottom-shear method, the Value  method is applied to calculate the stress of a frame under horizontal earthquakeWith the help of the bending moment delamination method respectively, the most unfavorable arrangement under the action of dead load and live load internal force calculation. Then seismic action effect of structural components with other basic combination of load effect and no earthquake effect and other load effect combinations of basic two kinds of circumstances, to combination of frame internal force, come to control internal force of frame beams. It was 2008, AutoCAD2007, PKPM2008 software calculation and draw the project construction and structure construction drawing.

Keywords：frame structure, earthquake, wind load, and lateral stability
