Finite Element Analysis of Concrete Structures

Numerical analysis of concrete using Finite Elements is being used increasingly to design and check structures. The complexity and scale of the analysis varies considerably, from simple linear analysis combined with code of practice rules to determine strength and deflection, to highly non-linear analyses that aims to predict strength and damage directly. Detailed concrete simulation, where the objective is to understand true behaviour as opposed to ensuring a conservative and approximate design solutions are reached, has gained particular interest in the assessment of existing structures and in designing precast components for repeated use. Here the cost of relatively expensive analyses is more than offset by avoiding demolition or by the accumulated savings associated with production engineering.

Structural concrete is often thought of as a simple, commonly available material. However, its varied constituents including aggregate, cement, water and reinforcement make it a complex composite material which can make it difficult to describe and to simulate. Now many Finite Element codes have proven capabilities for analysing the structural behaviour of concrete, but it can still be difficult to know how to make effective use of them, and it often remains a challenge applying them within mostly design code of practice frameworks.

The seminar covered the latest techniques being applied industrially, by leading practitioners, using case histories, but also provided some insight into the latest concrete modelling tools being researched and developed, and being incorporated into Finite Element software.
