Abstract

Abstract

A new cylindrical-cone steel cooling tower was proposed, and the concrete cooling tower was selected as a reference for the comparison study, which verified the technical achievability and structural reliability of the steel cooling tower, the results showed that its cost and duration were less than the concrete cooling tower. The calculation formulae for the axial, flexural, shear and torsional stiffness of the four-sided angle steel lattice type members was derived, on which the equivalent substitution principle and calculation method of the box-type thin-walled units were proposed, and the correction coefficients of the stiffness parameters were optained, which were analyzed and calibrated by using the finite element model. The results showed that the equivalent substitution of cross-sectional stiffness proposed in the paper had high accuracy and could meet the requcrements of engineering accuracy. By introducing the negative stiffness of axial force, the formula of calculated length coefficient applicable to general space structures was obtained.
