A pultruded fiber reinforced polymer plastic (PFRP) structural is one of the most widely used composite member in construction. In generally, PFRP members is composed of plate elements so that it needs to evaluate stability problems when they are used by construction members. On the other hand, creep effect may be occurred in PFRP members under sustained load. Primary to experiment for PFRP creep, previous works are studied. In the previous work related to buckling of PFRP member, it can be calculated buckling strength of PFRP members when it is known that material property of longitudinal and transverse direction of PFRP members. The researches for creep behavior of PFRP has been conducted and time-dependent degradation elastic moduls can be predicted by the empirical equation. In this study, it will be conducted creep test for PFRP and time-dependent stress-strain relationship will be plotted. It is expected that long-term buckling behavior of PFRP is evaluated by theoretical and numerical method such as finite element method.
