In recent years, composite columns have been used to achieve greater efficiency in many major structures in the United States. Simultaneously, the technology of high strength concrete has advanced rapidly and several important structures have been constructed using high strength concrete. The advantages of high strength concrete and composite construction can be combined to achieve even further efficiency, particularly in the columns. The combinations is composite columns with high strength concrete. In these columns, the concrete will provide extra and stability in compression and the steel will supply strength, stiffness as well as ductility. The objectives of the research are to study behavior and to develop guidelines for design of composite columns with high strength concrete. The objectives will be met by conducting experiments and analyses on a series of columns have configurations representative of those occurring in practice. A total of sixteen specimens will be tested. The specimens will have W shapes encased in the high strength concrete. Using the test results and analytical correlations of the results, current design procedures for composite columns will be modified or new procedures will be formulated.

近年来，组合柱已被用于实现 在美国的许多主要结构中提高效率。 同时，高强混凝土技术的发展， 发展迅速，一些重要的结构已经 使用高强度混凝土建造。 高的优点 高强度混凝土和复合结构可以结合起来， 实现甚至更高的效率，特别是在塔中。 组合体为高强组合柱 混凝土 在这些柱子中，混凝土将提供额外的， 压缩稳定性和钢将提供强度， 刚度和延展性。研究的目标 是研究行为，并制定设计指南， 高强混凝土组合柱 目标 将通过对一系列 柱具有代表发生在 实践 将对总共16个样本进行试验。 的 试样将具有W形状， 混凝土 使用的测试结果和分析的相关性 结果，目前的复合柱设计程序将 修改或制定新的程序。
