第一章 结构布置和计算简图

本教学楼跨架的承重方案为横向跨架承重方案

平面布置图

1.2梁丶柱截面尺寸的初步确定

1.2.1梁截面的尺寸的初步确定

横向框架梁

(1)、截面高度h

h=L。

h₁=L₁=×7350＝612.5~918.75mm

h₂=L₁=×3300＝275~412.5mm

取h₁=700mm，h₂=400mm

(2)、截面宽度

b₁=h₁=×700＝233~350mm

取b₌250mm

纵向框架梁

(1)、截面高度

h=L=×4000＝333~500mm 取h=500mm

(2)、截面宽度·

b=h=×500＝166~250mm

取b₂= b₁=250mm

1.2.2柱截面尺寸的初步确定

在初步估算柱截面面积时，应满足下式：

式中：

Nc——考虑地震荷载组合时的轴力设计值，Nc=C⋅N；

C——弯矩对框架柱轴力的影响，中柱扩大系数取1.1，边柱取1.2；

μ ——轴压比，本设计抗震等级为三级，取μ =0.75；

N = n×(12 ~14)kN /m2 ⋅ S；
