The research proposal is for funding to cover part of the cost of a second phase of testing to document behaviour of reinforced concrete block construction built using a new self-reinforced concrete block (SRB). The "self reinforcing" consists of a perforated tubular shaped metal confining device that is embedded within the body of hollow concrete block during manufacture using standard block making equipment. This form of reinforcing within manufactured block had not been successfully attempted prior to the initial research phase of this research. Its purpose is to improve the performance of concrete block construction under earthquake loading so that this form of construction can better compete with other structural building systems.

这项研究建议提供资金，以支付第二阶段测试的部分费用，以记录使用新的自增强混凝土砌块(SRB)建造的钢筋混凝土砌块的性能。这种“自增强”装置由一个穿孔管状金属约束装置组成，该装置在使用标准砌块制作设备的生产过程中嵌入混凝土空心砌块体内。在本研究的初始研究阶段之前，还没有成功地尝试在人造砌块内进行这种形式的加固。其目的是为了提高混凝土砌块结构在地震荷载作用下的性能，使这种结构形式能够更好地与其他结构建筑体系竞争。
