Improving the fire endurance of concrete block masonry walls towards next-generation performance-based fire standards

该项目旨在提高历史证明的混凝土砌体单元在防火隔墙中的弹性。砌体材料作为一种有效的建筑防火屏障，在上个世纪得到了广泛的应用。拟议的研究计划在未来五年内完成，由加拿大砌体设计中心（CMDC）和加拿大混凝土砌体生产商协会（CCMPA）代表的加拿大砌体行业合作。本研究项目的目标是：制定下一代砌体防火性能标准，改进防火砌体组合设计和施工，优化砌体单元的耐火制造，并促进对火灾损坏砌体进行可靠的灾后评估。将对全尺寸非承重（隔墙）砌块和小尺寸砌块的防火性能进行一系列实验测试，以量化各种参数对典型和原型混凝土砌块和砌块的传热传质、耐火性能、力学行为和残余强度的影响。

This project aims to improve to upon the historically proven resilience of concrete masonry units in fire separation partition walls. Masonry materials have been relied upon extensively over the last century as an effective form of fire barrier in buildings. The proposed research is scheduled to be completed over the next five years through collaboration with the Canadian masonry industry as represented by: Canada Masonry Design Centre (CMDC) and Canadian Concrete Masonry Producers Association (CCMPA). The goals of this research project are to: develop the next-generation of masonry fire performance standards, improve fire-rated masonry assemblage design and construction, optimize masonry unit manufacturing for fire resistance and facilitate robust post-disaster assessment of fire damaged masonry. A series of experimental tests will be conducted on the fire performance of full sized non-loadbearing (partition) masonry walls, and small-scale assemblages to quantify the effects of a variety of parameters on heat and mass transfer, fire endurance, and mechanical behavior and residual strength of typical and prototype concrete blocks and masonry assemblages.
