Information Systems for Repair Alternatives and Initial Cost Estimation of Damaged Building Structures

Abstract

The evaluation of existing structures for repair and strengthening results in the application of the most economical and effective repair techniques. The main focus is the existing buildings in seismic areas. The method of repair or strengthening depends on the damaged structural system, structural (life safety) issues, applicable seismic building code requirements, restrictions in available methods, and architectural and construction requirements. The consideration of new techniques, previous technical information on repair methods, experience of experts, and updated cost information are important in the evaluation. The most cost-effective schemes cannot be determined by choosing the most economical means to repair each component; an integrated approach is necessary. Also, recently the use of computers and networks to share the information are increasing. A knowledge-based information system has been developed for the integrated solutions. The level of damage is determined from the damage and structural information. In the evaluation, major damage conditions are grouped as ground damage, foundation damage and superstructure damage, and then these groups are divided into subgroups. Each repair method is represented by a specific format to determine the damage information index. The developed software is a self-modifying and learning system as a result of the data stored for common types of damaged buildings. The use of information systems results in rapid and effective initial cost estimation of repair methods.
