Abstract
In this study,a construction industry modernization training base as the research object,using the numerical model to calculate the mechanical properties of fabricated concrete columns,the conclusions are as follows:the numerical model established by the spring element and the bar element can not fully reflect the situation of the field test,which results in the stiffness and ductility of the simulation results of the fabricated concrete column in the forward loading section are larger than normal,thee reverse reloading section is smaller,making its energy dissipation less than the field experimental results.When the specimens are subjected to cyclic loading,there are holes in the prefabricated concrete columns with grouting defects,which lead to the sliding between the steel bars and the concrete and reduce the bearing capacity.关键词
