The application of the high tensile steel to the structural member has been much increased. The use of the high tensile steel increases the working stress level and the deformation. In these circumstance, the adequate evaluation of the detail structural design is becoming important. As one of these subjects, there is the strength evaluation for applying pad plates installed on upper deck as foundation plates of the pipe support and etc. First, in this study, the fine meshed FE analysis using solid elements around the pad plate is carried out, and the stress distribution is minutely investigated. Secondly, the simplification of the modeling by using plate elements is studied. And it is confirmed that the result of plate elements analysis is accurate in comparison with that of solid elements analysis. As the result of these studies, the practical and simplified evaluation method of stresses around pad plates is established.
