Taking the large-span cantilevered truss structure of Nanning Jiangnan Wanda Plaza A1A4 as engineering example, the steel bar stress, concrete strain and deflection during construction are monitored. Meanwhile,the large-span cantilevered concrete truss structure is simulated by finite element software. Through the chart analysis of structure form and the monitoring value of difference, the monitoring and simulation values are compared,and the construction process,the change rule of structure internal force and deflection are put forward, which demonstrate the security and stability of the large-span cantilevered concrete structure.
