Abstract

This presentation focuses on the evaluation and retrofit design practices for concrete buildings using FRP as a seismic strengthening solution. Current design practices for FRP composites focus on a force-based design approach, with limited attention to detailing of FRP. Recent large-scale tests of FRP strengthened concrete elements performed in the US and New Zealand highlight the relevance and importance of adequately detailing FRP with FRP anchorage.

This session will cover seismic detailing for FRP strengthened diaphragms, shear walls and slab-wall connections.

Objectives:

• Key aspects of quality control and inspection practices for field FRP applications.

• Summary of large scale tests for concrete diaphragms and shear walls strengthened with FRP.

• Importance of adequately anchoring FRP for seismic applications.

• Conceptual design example.

Biographies:

Enrique is a structural engineer with extensive experience in the seismic behaviour and strengthening of concrete structures, which was the topic of both his Master and PhD projects. He is currently a Senior Lecturer at the University of Auckland, where he combines his role as Associate Dean for Teaching and Learning with extensive research mainly related to strengthening and seismic behaviour of concrete structures, and sustainability of concrete. Outside of his academic career, Enrique is director of FRP Designs, an engineering consultancy focused mainly on seismic strengthening and behaviour of structures.
