摘要
Abstract
Movable windbreak lattice structure is an innovative solution to the shortage of the traditional windbreak facilities.The stress acting on this new structure was analyzed and calculated by using 3D3S software and PKPM software,which showed that long frame columns mainly bore an axial tensile force up to max.38.787 kN while short frame columns and diagonal braces bore an axial compressive force up to max.42.491 kN under load conditions.Positive and negative bending moments in direction-X were located at both sides of the upper part of long frame columns,the maximum positive value was close to the absolute value of the maximum negative value,which led to good structure symmetry and high structure stiffness.The displacements and stresses of all members complied with the specifications under various loads,namely,the above values always varied within a safe range.关键词
