The project aims to investigate the behaviour of and design hybrid multiple-tube concrete columns, a form of column. These columns allow the use of small circular high-strength steel tubes, readily available in the market, to suit the specific needs of construction projects of various scales. In the column, a durable outer tube made of fibre-reinforced polymer (FRP) composites protects steel tubes, and their high yield stress can be fully exploited through section configuration. The new column is expected to enable wider, safer and more economical use of FRP and high-strength steel, and meet demands for resilient civil infrastructure.

该项目旨在调查和设计混合多管混凝土柱的性能，这是柱的一种形式。这些柱允许使用市场上随处可见的小圆形高强度钢管，以满足各种规模建筑项目的特定需求。在柱中，由纤维增强聚合物(FRP)复合材料制成的耐用外管保护钢管，通过截面配置可以充分发挥钢管的高屈服应力。预计新立柱将能够更广泛、更安全、更经济地使用玻璃钢和高强度钢，并满足对弹性民用基础设施的需求。
