Y - brace has the least effect on the deformation of transverse beam and theY - braced frame has the highest load - carrying capacity.
同时Y形支撑对框架横梁的变形影响最小，极限承载力也最高。

A method to analyze behaviors of beam-slab braced foundation pits was proposed considering the effect of construction process. A 3d FEM program based on the model was developed.
