Abstract： In order to calculate the second order horizontal drift caused by the second order effect of the tower body，the approximate calculation formula is obtained by theoretical derivation in combination with the actual situation.The rationality of the formula is verified by field test and simulation of the QTP125 tower crane.The results show that the formula can be used to quickly calculate the second order drift of the tower body under static state in practical engineering，and provide a reference for the safety design of the tower crane structure.
