Experimental Studies on Polyester Geo-Fabric Strengthened Masonry Elements
The masonry elements exhibit high compression and weak tensile strength properties. The tensile strength of masonry elements can be improved by providing necessary reinforcements. The behavior of masonry in addition to any relevant materials needs significant studies. The present work focuses on enhancing the performance of masonry wallets by providing reinforcement with polyester Geo-fabric. The present experimental investigation shows comparison between conventional masonry elements and masonry elements strengthened with polyester Geo-fabrics. Polyester geo-fabrics are Geo-synthetic materials used in many infrastructure works for enhancement of tensile properties of structural members. The various masonry elements considered for experimental investigations are prisms, triplets and wallets. The fabrics were placed at interfaces of bed joints in prisms and triplets, in wallets the strengthening was done by applying double-sided configuration by considering one-third distances on each face perpendicular to bed joint. Performances of polyester geo-fabrics reinforced specimens are compared with conventional specimens in terms of strength and failure mechanisms.
