摘要：
This paper presents the results of an experimental investigation pertaining to the long-term behavior of pultruded fiber-reinforced polymeric materials subjected to longitudinal compressive loading. Material coupons cut from a pultruded vinylester/E-glass I-shape section were subjected to axial compressive loads at various stress levels for time durations up to 10 000 h. The strain measurements over time were recorded and compared to a practical power law formulation, with good agreement. A predictor design equation for the time-dependent longitudinal modulus was developed on the basis of the experimental results. (C) 1998 Elsevier Science Ltd. All rights reserved
