Abstract
This is a comprehensive office building in TAIZHOU . It is a multi-layer reinforced concrete frame. It has five stories, the height of the first storey is 5.5 meters, and the second、 third and the fourth storel is 3.6 meters ,the fifth storey is 4.0 meters. The height of the whole building is 24.7 meters.
The purpose of this design is to do the anti-seismic design in the longitudinal of axis 5. When the directions of the determined,firstly the weight of each floor is calculated.Then the wind load in calculated by D method,then making the amount of the horizontal seismic force can be got by way of the bottom_shear force method.The seismic force can be assigned according to the shearing stiffness of the frame of the different axis. Then the internal force (bending moment,shearing force and axis force)in the structure under the horizontal loads can be easily calculated.After the determination of the internal force under the dead and live loads,the combination of internal force can be made by using the Excal software,whose purpose is to find one or several sets of the most adverse internal force of the wall limbs and the coterminous girders,which will be the basis of protrating the reinforcing drawings of the components.The design of the stairway is also be approached by calculating the internal force.
