Structural Renovation of Buildings

Introduction

This CITED Civil & Construction Engineering training seminar will present methods for inspection and evaluation of buildings and diagnose the reason of concrete deterioration or the corrosion of the steel bars, to develop preventive maintenance program. The renovation of the reinforced concrete structures has become common in recent years due to the development in technologies, materials and the techniques for maintenance and repair.

In this training workshop, the causes of structure deterioration will be discussed concentrating on the reason of corrosion and new protection methods to the steel bars. All the repair and renovation methods will be covered theoretically and practically and obviously discussed its advantages and disadvantages and how to use the suitable method. The case study explains practically who can we diagnosis the reason of deterioration and take the decision of repair and choose between different alternatives. 

Objectives

By the end of this training course, participants will be able to:

• Understand modern and effective procedures for renovation of the building

• Know the structure defects and cracks and diagnosis the reason for deterioration

• Diagnose the problem and provide a repair solution

• Familiarise with up-to-date renovation methods for concrete and steel structures
