Shear wall system is a common seismic force resisting system that is used for both reinforced masonry (RM) and reinforced concrete (RC) buildings. RM shear walls can provide a considerable level of ductility like RC walls, especially for walls with boundary elements. The latest provisions of the Canadian Standard for Masonry allowed a higher level of ductility for RM shear walls based on their ductile response. This paper aims to estimate the quantities of construction materials required for RM shear walls compared to those of RC walls. Three multi-storey RM shear wall buildings with different heights located in three different cities in Canada were selected. 5-, 10-, and 15-storey buildings were located in Toronto, Montreal, and Vancouver cities which represent three different levels of seismic hazard. For each building’s height and location, the RM shear walls were designed with the level of ductility that results in the least construction material quantities. The analysis and design procedures were repeated for each case when RC material was used. The amount of construction materials used for the shear walls of each building was evaluated for both RM and RC cases and they were compared. Moreover, the cost of labour and temporary works for RM and RC shear walls was estimated and compared. The comparisons showed that RM shear wall construction can be as economic as the RC one for different walls’ ductility levels.

钢筋砌体与钢筋混凝土剪力墙的材料数量

剪力墙系统是一种常见的抗地震力系统,可用于钢筋混凝土(RM)和钢筋混凝土(RC)建筑物。RM剪力墙可以像RC墙一样提供相当高的延展性,尤其是对于带有边界单元的墙。加拿大砌体标准的最新规定允许RM剪力墙基于其延性响应而具有较高的延性。本文旨在估算与RC墙相比,RM剪力墙所需的建筑材料数量。选择了位于加拿大三个不同城市的三座不同高度的多层RM剪力墙建筑。5层,10层和15层的建筑物分别位于多伦多,蒙特利尔和温哥华的城市,代表三种不同级别的地震灾害。对于每个建筑物的高度和位置,RM剪力墙的设计具有一定的延展性,从而使建筑材料用量最少。使用RC材料时,针对每种情况重复进行分析和设计程序。对于RM和RC案例,评估了每座建筑物的剪力墙所用的建筑材料数量,并进行了比较。此外,对RM和RC剪力墙的人工和临时工程成本进行了估算和比较。比较表明,对于不同墙体的延性水平,RM剪力墙的建造与RC一样经济。对于RM和RC案例,评估了每座建筑物的剪力墙所用的建筑材料数量,并进行了比较。此外,对RM和RC剪力墙的人工和临时工作成本进行了估算和比较。比较表明,对于不同墙体的延性水平,RM剪力墙的建造与RC一样经济。对于RM和RC案例,评估了每座建筑物的剪力墙所用的建筑材料数量,并进行了比较。此外,对RM和RC剪力墙的人工和临时工作成本进行了估算和比较。比较表明,对于不同墙体的延性水平,RM剪力墙的建造与RC一样经济。
