Abstract

Glass fibre reinforced plastic (GRP) structural members are currently being produced successfully by pultrusion and are now used in an increasing number of civil engineering applications. Measurements of the orthotropic mechanical properties of the GRP box section are necessary for use in the numerical modelling of connection. Pultruded GRP structural sections may not possess the dimensions necessary for the extraction of standard length coupons for tensile testing. In this study, initial experimental tests have been conducted using ASTM D3039 specimens to provide the experimental longitudinal tensile properties (elastic modulus, Poisson's ratio, strength) of pultruded GRP box section. The transverse tensile properties have been determined using the proposed short coupon following validation against the ASTM D3039 data.

Özet

Cam fiber takviyeli plastik (CTP) yapı elemanları ön gerilmeli olarak üretilmekte ve birçok inşaat mühendisliği alanında kullanılmaktadır. Birleştirmelerin nümerik analiz ve dizaynları için bu malzemelerin ortotropik mekanik özelliklerinin bilinmesi gerekir. Çekilmiş cam fiber takviyeli yapı profilleri çekme deneyi için gerekli standart numune boyunu vermeyebilir. Bu çalışmada, ilk olarak ASTM D3039 numuneleri kullanılarak çekilmiş CTP malzemenin boyuna olan mekanik özellikleri (elastik modülü, poisson oranı ve dayanım) deneysel olarak belirlendi. Enine olan mekanik özellikler ise belirlenmiş olan boyuna kısa kuponların ASTM D3039 kuponları ile uyumu sağlandıktan sonra bulundu.
