Design Method of Horizontal Braces Unlocated at Middle of Columns with Fixed-Ended Column Base

Abstract:

A large number of column-bracing systems for the horizontal braces unlocated at middle of columns with fixed-ended column base were modeled and analyzed by second-order analysis using finite element method, in which the random combination of the initial imperfections between columns and horizontal braces was well considered by Monte Carlo method. According to the analysis results, two kinds of instability modes of column-bracing system have been found, probability density function of the horizontal bracing forces unlocated at middle of columns with fixed-ended column base is established based on probability statistics, and the design formula of horizontal braces unlocated at middle of columns are also proposed.
