Currently, the largest factor negatively affecting the potential for growth of load-bearing block construction is the change in design requirements related to seismic loading. According to the 2005- National Building Code of Canada (NBCC) both reinforced and unreinforced masonry structures are considered to be particularly vulnerable to seismic damage. The new seismic design provisions of the NBCC have partially resulted from the widely held view that masonry structures have limited ductility, and some examples of structural masonry failures. This has created a situation where a significant amount of research is needed to increase the ductility of masonry structures and document the resulting improved performance.

目前，对承重砌块结构增长潜力产生负面影响的最大因素是与地震荷载相关的设计要求的变化。根据2005年加拿大国家建筑规范（NBCC），加固和非加固砌体结构都被认为特别容易受到地震破坏。NBCC新的抗震设计规定部分是由于人们普遍认为砌体结构延性有限，以及一些砌体结构失效的例子。这就产生了一种情况，需要大量的研究来增加砌体结构的延展性，并记录由此产生的性能改进。
