This design is a tree-man teaching building, for the frame structure, a total of six floors. Regional anti-seismic fortification intensity is 8 degrees, the first group of earthquake groups, the site category is class I site. Basic wind pressure 0.45kn//m', basic snow pressure 0.40kn//m'.According to the building structure specifications, the construction data are calculated by hand and calculated by electricity. The basic contents are: general description, the plane of the building, facade. Internal force calculation, rib calculation, etc. Structural design is mainly internal force calculation and cross-sectional design, internal force calculation through data to calculate seismic effect and gravity load, the use of "torque distribution method." The load combination is then calculated and the section is calculated. There are mainly component sections and component design, in addition to the detail smaller dimensions of the design.
