abstract

This design topic is Baoan Pu Park Building No. 4 building structure design, a total construction area of about 3300 square meters, building 6 floors. The design content mainly includes the structure design part and the internal force calculation part. The process of calculation and calculation results of comprehensive calculation, combination of calculation and its effect are calculated, the seismic load calculation of constant load and wind load; structure design mainly completes the following tasks: internal force analysis and design standard of cast-in-place floor; calculation section of beam and column design and reinforcement of the internal force; analysis and design of stairs; determination, and internal force analysis and design of foundation form; the final construction plan drawing structure. Firstly, according to the specification of estimation of column and beam sizes; access to information with their own task load statistics; according to the wind load calculation of building structure load specification method of column lateral stiffness of D was calculated by D value, and the displacement under the wind load were checked; according to the specifications of the horizontal earthquake can be used the bottom shear method to calculate; calculating the dead load moment under the action of stratified, and adopt the method of structural mechanics and the free body obtained according to the method of beam column shear, shear diagram by using structural mechanics balance conditions obtained from taking body beam column axial force; with the structural mechanics solver to complete the internal force in the live load the calculation of bending moment; according to the specification by the inflection point method in the calculation of wind load and calculate shear force and axial force of columns; complete internalforce under earthquake with the structural mechanics solver Calculation; according to the standard of internal force combination to find the adverse internal force; finally, the beam column plate reinforcement and stair foundation reinforcement and its design.

Key words: internal force combination;internal force calculation;mechanism design; reinforcement
