1 - Review and further analysis of concrete composite columns

Abstract

With the continuous progress of modern society and the continuous development of construction industry, various concrete composite columns have been widely used in practical engineering construction, such as steel-concrete composite columns, fiber reinforced polymer (FRP)-confined concrete composite columns, and FRP-steel-concrete composite columns. In these concrete composite columns, the interaction relationship between concrete and FRP or steel can make complementary advantages effect, and lead to the excellent mechanical properties and durability of the concrete composite columns. In order to understand the concrete composite columns, this chapter reviews and analyzes a variety of section forms, and puts forward the research direction of concrete composite columns in combination with corresponding tests and theoretical research. It also presented supplemental test studies to identify some unknown behavior. Based on the comprehensive review and analysis, the purpose and significance of this book are revealed at the end.
