问题 单项选择题

A.墙承重结构
B.骨架承重结构
C.内骨架承重结构
D.空间结构

答案

参考答案:D

解析: 第一章工程构造第一节工业与民用建筑工程中关于民用建筑的分类。
[思路] 民用建筑按结构的承重方式分:墙承重结构、骨架承重结构、内骨架承重结构和空间结构,其中,空间结构是采用空间网架、悬索及各种类型的壳体承受荷载。
[易错] 如果考生对于民用建筑的墙承重结构、骨架承重结构、内骨架承重结构和空间结构这些承重方式的荷载传递方式没有记清楚,其他三个答案都可能会选错。
[拓展] 在单层工业厂房中,注意工业建筑按厂房跨度尺寸分可分为小跨度厂房和大跨度厂房,跨度小于或等于12 m的厂房是小跨度厂房,一般以砌体结构为主;跨度在15 m以上的厂房是大跨度厂房,15~30 m以钢筋混土结构为主,跨度在36 m及 36 m以上的厂房以钢结构为主。
