Power transmission tower main material joint strength determination method
The invention relates to a power transmission tower main material joint strength determination method; the main materials are connected through bolts and connecting plates; the determination method comprises the following steps: calculating a main material joint segment length so as to obtain a reduction coefficient; considering bolt shearing effect, and determining one side shear capacity and one side extruding carrying capacity of the single bolt; utilizing a pole stress diffusion angle to determine a stress diffusion distance, a stress diffusion width, and the width between a stress diffusion edge and the center; determining effective width and net area of the connecting plate, and determining net areas of inner and outer steel-clad so as to calculate the main material joint intensity; calculating the number of the connecting bolts, specifications of the inner and outer steel-clad, and the specifications of the connecting plate, thus determining a final main material connecting form. The power transmission tower main material joint strength determination method can effectively simulate member real force bearing conditions; sketch maps are provided, so the calculating formula is simple and understandable, and the design people can conveniently carry out pole calculation.
