Abstract This is a design for jinjiang college teaching building in zhenjiang。Total construction area is about 4608 sq。m。The building with steel frame structure, has five layers and each layer is 3。6 m high。 It has been designed for 50 years service life。The level of fire resistance rating and security is both secondary。Seismic fortification intensity of the structure is 7 degrees。The acceleration of Earthquake is 0。1 g。 The ground absolute elevation is the yellow sea height of 32 m, and the ground water is under the earth surface 3。0 meters。 The constant load, floor live load, seismic level, wind load and load combination effect are taken into account。 In the part of structure design ,I chose a common framework and the foundation to calculate。 I have finished the selection of structural system, structural layout, section size estimation, load calculation, lateral calculation, internal force calculation, check and the design of the reinforcement in PKPM computing work。Besides, I have completed the design of stairs, secondary member, and foundation 。 With software, such as CAD, PKPM , I finally mapped the construction and structure drawings。 In the late process, I learned TEKLA to draw steel details。
