Abstract

Located in ShenYang, this engineering is a steel structure teaching building which has a main body of four floors. All floors of the building are 3.9 meters high. The building has a total height of 19.5 meters with a plan view size of 48.2m×23.6m. In addition，The earthquake fortifying intensity of this engineering is 7 degree, and the basic earthquake acceleration of the design is 0.10g.

The main form of the structure is steel frame structure box-shaped. Splicing nodes were connected by welding bolt. The pressure plate - non-mix concrete floor slab was applied for the floor roof, light-weight aerated concrete block was selected as walls. Meanwhile, steel stairs were selected in the project. the structural design bases on graduation project requests, such as the capacity of resisting the earthquake. In the calculation, the solutions about earthquake computing is according to the aseismic code, which is our national nouns specifically speaking, the process of the structural design are as follows, judge the size of the member of structure, calculate the load, calculate the internal force, design the connection of members, design the single extended foundation under the column. When calculate the internal force, many loads are taken into consideration, such as the wind load, the seismic load, the snow load and etc;when check the steel member and the connections, the normal situation and seismic situation are both considered.

I also compare the results between hand count and software, so that I can know better about the difference between them. When calculate the deformation of the steel-concrete combinated beam, the beam is simplified as a simple supported beam.

Keywords：steel framed structure;the design of connections;the design of steel member
