The choice of optimum position of press bar on lateral support

用传递矩阵法计算了在各种支承下，变截面压杆有一个多余旁撑最佳位置选择；等截面压杆有一个或两个多余旁撑最佳位置的选择。这对工程实际有一定的参考价值。

This article calculated the choice of optimum position of a superfluous lateral support on variable section press bar and one or two superfluous lateral support on isosection press bar in all kinds of supports with the method of transmit matrix given by the writer in reference article, which has a definite reference value to the engineering reality.
