Development of Precast Concrete Segmental Columns to Resist Dynamic Loads

预制节段混凝土柱在结构中的应用，提高了施工效率和现场安全性，使施工质量得到了更好的控制，降低了施工成本，减少了现场破坏和环境影响。节段柱的抗震性能和抗爆性能还没有得到很好的研究。由于结构在使用期间可能会受到这样的荷载，了解其抗力能力对于结构安全至关重要。本项目旨在进行试验和数值研究，以研究预制节段混凝土柱在地震和爆炸荷载作用下的性能，并为此类柱在建筑和桥梁结构中的应用开发分析和设计方法。

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.
