Abstract

A methodology is presented for analytical calculation of creep behavior of plane frames made of glass fiber reinforced polymer (GFRP) profiles and an experimental study is carried out in order to evaluate the analytical calculation results. In order to account nonlinear viscoelastic material behavior, stress – strain – time relationship of plane frame is given and creep behavior of plane frame structure is investigated. Material coefficients for the creep functions are determined using three point beam bending test results. In order to validate the analytical approach, a plane frame made of GFRP profiles is tested under sustained loads for 100 days and displacements, strains are monitored. Strain and displacement values that are calculated using analytical method show good agreement with the full-scale test data.
