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 21.0 meters in height and the total floor area is 5870m2 .
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.
Keywords: frame; action of earthquake; internal force; design; reinforcement
