前言混凝土砌体为不燃体,具有持久的耐火性能,同时又施工经济,因此被广泛地指定为防火墙和防火屏障的构件。在《国际建筑规范》(IBC)[2]~[3]第7章中,对结构性耐火和隔火的材料及构件有具体规定。本TEK文件是在《混凝土和混凝土砌体构件耐火性能的评定》ACI216.1/TMS-0216[1](以下简称《标准》)规定基础上,介绍混凝土砌体构件耐火极限的计算
Preface Concrete masonry is a non-combustible body that has long-lasting fire resistance and economical construction and is therefore widely designated as a component of firewalls and fire barriers. In Chapter 7 of International Building Code (IBC) [2] ~ [3], there are specific provisions for structural fire-resistant and fire-blocking materials and components. This TEK document describes the calculation of the fire resistance limit of concrete masonry components based on the provisions of ACI216.1 / TMS-0216 [1] (hereinafter referred to as the “Standard”), “Assessment of fire resistance of concrete and concrete masonry components”
