Development of Precast Concrete Segmental Columns to Resist Dynamic Loads

在结构中使用预制节段混凝土柱可提高施工效率和工地安全，更好地控制施工质量，减少施工成本，减少对工地的干扰和对环境的影响。目前对节段柱的抗震和抗爆性能的研究还不多。由于结构在其使用寿命期间可能会受到此类荷载的影响，因此了解其抵抗能力对于结构安全至关重要。本计画旨在进行实验与数值研究，以探讨预制节段混凝土柱在地震与爆炸荷载作用下之性能，并发展此等柱在建筑与桥梁结构中应用之分析与设计方法。

Using precast segmental concrete columns in structures improves the construction efficiency and site safety, leads to better construction quality control, and reduces the construction cost, site disruption and environmental impacts. The performance of segmental columns to resist earthquake and blast loads is not well studied yet. As a structure might be subject to such loads during its service life, understanding its resistance capacities is essential for structural safety. This project aims to perform experimental and numerical investigations to study the performance of precast segmental concrete columns under earthquake and blast loads, and develop analytical and design methods for applications of such columns in building and bridge structures.
