Firs , hrough he f ield loading es on cas s eel join wi h large size used in spacial s ruc ures a Jiangbei In erna ional Airpor in Chongqing, he s resses on he surface of he cas join are ob ained. Then, he FEM analysis model es ablished by he Pro/ E sof ware is also performed o compu e he s resses a he same poin . Through he comparison be ween he calcula ed values and he es ed values, i is shown ha bo h of he values ma ch well. On his condi ion he in ernal s ress dis ribu ion can be deduced by he FEM resul . In addi ion, based on he FEM analysis considering he ypical defec of he cas s eel join , he effec of he defec upon he mechanical behavior of he join is inferred . Finally, combining he es and he analysis, he mechanical behavior of he cas s eel join is r
