摘要本工程为南方某繁华地段一拟建多层旅馆，按其使用功能将建筑分为五层。楼房标高为15.900m，总建筑面积约为4500m2。

本工程结构设计采用多层钢筋混凝土框架结构，基本步骤为：结构计算简图的确定；荷载计算；内力分析；内力组合；梁、柱截面配筋、板的设计、楼梯的设计、基础的设计以及结构施工图的绘制等。其中，内力计算考虑以下四种荷载作用，即恒荷载、活荷载、风荷载以及地震作用；柱、板的设计采用弹性理论；梁的设计采用塑性理论；楼梯选用板式楼梯；基础选用十字交叉条形基础。在进行截面抗震设计时，遵循了强剪弱弯，强柱弱梁，强节点弱构件的设计原则，且满足构造要求。50889

ABSTRACT This engineering is an office building of many layers in Dongying City . According to the function, the construct consists of five layers. The building is 15.9 meters in height and the total floor area is 4000m2 .

Reinforced concrete frame structure is adopted in this engineering. The design includes determination of structure calculating diagram; calculation of load; analysis of internal force; combination of internal force; reinforcement for beams and columns; the design of slab, stair and basement; the drawing of structural working plan. Dead load, live load, wind load and earthquake action are considered. The design of beams is based on plastic analysis. Slab stair and strip foundation are selected in this design. In the seismic design, the design principle of “strong column and weak beam, strong shear and weak bending, strong joint week member” is obeyed. And the cross-section can meet the demand of construction.
