- Abstract:
- Optimization studies on wind-sensitive structures focus on high-rise buildings,and large span spa-tial structures have seldom been involved. For optimization problems with a lot of design variables,the criteriamethod is usually effective. Design theory and numerical program of wind resistant optimization for complexspatial truss structures are firstly presented.Then,a real double-layer cylindrical reticulated shell is optimizedbased on the equivalent static wind loads from wind tunnel tests,discussing the influences of area lower limitand full stress step.The results show that the total structural weight is decreased by 48% when the maximumstress is less than the initial correspondent. By setting area lower limit,suitable area distribution is obtained,and material performance is fully made use of to achieve less structural weight.
