| Abstract: | The braced system is most frequently used for various types of high-rise steel structures.A typical model of steel frames is set up.Through calculating top displacements of a 6-storeyed frame and a 20-storeyed frame with identical brace layout,it is examined that the effects of vertical braces on the bearing capacity and lateral stiffness of the frames with different heights,and the effects of the different brace forms on the bearing capacity and lateral stiffness of the frames with identical heights.And on the basis of which the influencing law of the brace layout forms for high-rise steel structure on lateral stiffness of the frames is also explored. |

| Keywords: | brace layout lateral stiffness of frames influence |
