| Abstract: | A new type hub-shape joint for single layer lattice shells is put forward on the basis of practical projects.Full scale experiments of the joints are conducted.The ultimate load carrying capacity of the joint is analyzed by using finite element program ANSYS.The results of experiments and FEM are compared.The influence of the joint diameter and wall thickness on compressive load carrying capacity is analyzed.Based on the analytical results of 121 models of joints which have different diameter and wall thickness of the new type hub-shape joints,a reasonable formula of compressive ultimate bearing capacity of the joints is presented.Based on experimetal results the measurements improving tensile behavior is proposed. |
