The bracing force of top horizontal braces supporting a row of columns under the only vertical load has been investigated in this paper. A large number of one-story longitudinal column-bracing systems were modeled and analyzed by second-order analysis using finite element method, in which the random combination of the initial imperfections between columns and braces was well considered by Monte Carlo method. According to the analysis results, three kinds of instability modes of one-story column-bracing system have been found, triple-normal probability density function of the top horizontal bracing forces is established based on probability statistics, and the design bracing forces are also obtained. A check method based on the vertical load analysis is supplied for the top horizontal bracing forces which are usually designed by the longitudinal horizontal load.
