Damage Analysis of Pultruded Fiber Reinforced Polymer Connections

Pultruded Fiber Reinforced Polymer (PFRP) composites are attractive replacements for metals, especially steel members, in corrosive environments. One of the most crucial aspects of using pultruded sections is their connections, which plays a vital rule in ductility of structures. The design and analysis of composite connections involve high degree of complexity due to anisotropic, inhomogeneous properties of the material. Therefore, special attention is required for this purpose. In this paper, a numerical simulation using Abaqus FE software is employed to study the behavior of connections of pultruded fiber reinforced polymer composites. A damage model is used to study the effect of connection elements of composites in the connection capacity load. In this model, different modes of failure of composite components are accounted for to capture the behavior of the structure as the load increase. During the analysis, material properties are degraded as the damage evolve based on a preset’s criterion.
