Experimental and numerical studies on single-layer reticulated shells with aluminium alloy gusset joints
AbstractSingle-layer reticulated shells with aluminium alloy gusset (AAG) joints have a significant application prospect in spatial structures. To investigate their buckling behaviour, a single-layer reticulated shell with AAG joints subjected to a concentrated load at central joint was tested. The tested shell was a K6 shell with 5 rings, 8m span and 0.5m height. Its failure mode, buckling behaviour, internal force distribution of members, stress distribution of plates and joint stiffness were discussed. Finite element (FE) method implemented in the non-linear code ANSYS was adopted for the further investigation of single-layer reticulated shells with AAG joints. The FE procedure was accurately calibrated on the basis of the available experimental results. To develop a deep understanding, parameter studies considering the influence of joint bending behaviour on the buckling behaviour of single-layer reticulated shells were conducted.
HighlightsA single-layer reticulated shell with AAG joints was tested.Its failure mode, buckling behaviour, and joint stiffness were discussed.The shell buckling belonged to the snap-through buckling.The influence of joint behaviour on the buckling behaviour of shells were conducted.The bolt fixed phase of AAG joints affected the shell buckling behaviour greatly.
