The task of representing a real structure by an idealized model is an important aspect of engineering work. Most of the structure consisting of slender members like bridges, towers and ladders are assembled by bolting and welding. On the finite element analysis (FEA) of these structures, LINK elements which is assumed to be axially loaded are widely used. This paper presents the effect of element type used in the FEA of large scale structure. FEAs modeled with LINK element and BEAM element are conducted for several structures to compare the solutions and investigate the bending effect. In order to verify the results calculated by FEA, structural test by using strain gage apparatus is conducted for a 52 meter-high ladder structure for fire protection. Stresses at selected locations are compared with those by FEA.
