The masonry industry in Canada contributes $1 billion annually towards economic activity, and employs thousands of skilled laborers, contractors, manufacturers, and engineers directly, with many more employed by spin-off companies and within the necessary supply chain. However, the increasing gap in materials, design, and construction methods for masonry as are being used in Canada and the U.S. is affecting the Canadian industry, and potentially holding back synergies and cost savings that may otherwise be available.The Canadian Masonry Design Centre and the National Concrete Masonry Association in the U.S. have therefore committed to harmonizing design requirements for masonry as are included in Canadian Standard CSA S304 - Design of Masonry Structures and U.S. code TMS 402 - Building Code Requirements and Specifications for Masonry Structures. While some differences between these two codes are isolated and so quite specific, others, such as the method by which each has been calibrated for structural safety are intrinsic, and makes a comparison between the two codes difficult without conducting a thorough analysis. Initial meetings between the two organizations have identified the need for the following research objectives to be achieved: (1) to conduct a comparative analysis of slender concrete block wall designs resulting from use of the two codes, (2) to evaluate the compressive strength of masonry prisms based on the requirements of CSA S304 and ASTM C1314 specifications, and (3) to examine the effective flange width to be used for the analysis of partially grouted and reinforced masonry walls constructed with ASTM C90 blocks that are subject to combined axial load and bending.In total, training will be provided to 1 Ph.D. and 2 M.Sc. students in an area of strategic and economic importance to Canada.

加拿大的砖石行业每年为经济活动贡献 10 亿加元，并直接雇用数千名熟练工人、承包商、制造商和工程师，还有更多的人受雇于附属公司和必要的供应链。 然而，加拿大和美国使用的砌体材料、设计和施工方法之间日益扩大的差距正在影响加拿大工业，并可能阻碍本来可以实现的协同效应和成本节约。因此，加拿大砌体设计中心和美国国家混凝土砌体协会致力于协调加拿大标准 CSA S304 - 砌体结构设计和美国规范中包含的砌体设计要求 TMS 402 - 砖石结构建筑规范要求和规范。 虽然这两个规范之间的一些差异是孤立的并且非常具体，但其他差异（例如每个规范的结构安全校准方法）是固有的，并且在不进行彻底分析的情况下很难对两个规范进行比较。 两个组织之间的初步会议已确定需要实现以下研究目标：(1) 对使用两个规范所产生的细长混凝土砌块墙设计进行比较分析，(2) 根据 CSA S304 和 ASTM C1314 规范的要求评估砌体棱柱的抗压强度，以及 (3) 检查用于分析部分灌浆和灌浆的有效翼缘宽度。 使用 ASTM C90 砌块建造的加固砌体墙，承受轴向载荷和弯曲的综合作用。总共将为 1 名博士提供培训。和 2 个硕士学位对加拿大具有战略和经济重要性的领域的学生。
