Abstract
The book mainly including eight parts: the selection of the structure, the
calculation of framework structure under the horizontal loads,the internal forces
calculation under the vertical loads, the internal forces composition of horizontal
framework ,the design of section size ,the design of plate,the design of basis,the
design of staircase.
The object of design is five-story frame structure. Choose one load of the
frameworks to calculate.
The calculation of framework structure including: The initial assurance for the
size of the beam, the plate and the column; The calculation of the standard values
of gravity load ; The sway stiffness calculation of the horizontal framework ; the
internal forces calculation and the checking of sway under the horizontal
earthquake forces ;the checking of sway under the horizontal load of wind.(Wind
load is out of consideration when the internal forces composition)
The internal forces composition of horizontal framework maily including: the
calculation under the live load and the constant load .
The internal forces composition mainly is the composition of horizontal
earthquake forces, constant load and live load.
The section design including: the design of the beam , column .the design of
beam including:the checking of positive section and oblique section.
The design of column including: the checking of axial compression ratio and the
positive section and the oblique section,the design of node.
When design the plate considers it’s two-way plate.
Basis design including: the calculation of carrying capacity, punching and
reinforcement.
The design of staircase including: the design of bench,the beam of
platform,the plate of platform and calculation of reinforcement of staircase.
