Abstract
To enhance construction safety,LNG storage in Rudong of Jiangsu Province was adopted as a practical work,and it was analyzed by nonlinear finite element method to research overall and local stability performance,as well as stress and deformation under the action of wind load and self-weight.Results indicated that deformation was tiny when reinforcement maintained as an overall ring,stresses caused by vertical bending moment and tension of bottom tie wire were also in the safe range.However,axial forces of lap reinforcement in adjacent steel mesh exceeded the ultimate bearing capacity of tie wire.Hence,tie wires were ruptured,single mesh lost lateral connection and turned into monolithic status as the destruction of the overall structure.Further more,monolithic steel mesh was led to collapse by the damage of bottom connection.So,in order to prevent connection failure and ensure construction safety,the overlapping parts of steel mesh should be taken more reliable measures.
