Structural Capacity

A proposed supplement to ASCE/SEI 41 Seismic Rehabilitation of Existing Buildings has been developed for the purpose of updating provisions related to existing reinforced concrete buildings. Based on experimental evidence and empirical models, the proposed supplement includes revisions to modeling parameters and acceptance criteria for reinforced concrete beams, columns, structural walls, beam-column joints, and slab-column frames. The revisions are expected to result in substantially more accurate and, in most cases, more liberal assessments of the structural capacity of concrete components in seismic retrofit projects.

Regarding the importance of nonstructural elements in the vulnerability of buildings and their seismic safety level, on one hand, and the extensive damage to some of these elements in the 26 December 2003 Bam earthquake, on the other, this paper reviews the particular features of nonstructural elements in Iranian buildings and then presents the results of a thorough survey of their behavior and the damage they sustained in the city of Bam. Finally, based on the results of this survey, some recommendations are made that will be useful for modification of the “Guidelines for the Seismic Retrofit of Existing Buildings,” which is the only official reference on this topic used currently in Iran.

The World

Earthquakes are one of the biggest life-threats in the world. The effect is immediate, with little to no warning about damage plans and the collapse of buildings/structures. Prevention of earthquake-related disasters has become more and more important in recent years. Preventing disasters involves reducing seismic risk by retrofitting existing buildings. Seismic retrofitting has now become a crucial issue. Retrofitting helps improve the structure's strength, resistivity and overall lifespan. Recent occurrences of earthquakes in various parts of the world have clearly shown the urgency of repairing deficient seismic structures. The paper summarised many past studies in the form of a seismic strengthening solution, based on the type of beam-column joints, retrofitting technology and fiber reinforced polymers (FRP).

Specific Challenge

A comprehensive database for the specific challenge of cost prediction when undertaking seismic retrofitting of existing buildings is presented. A rigorous data collection effort performed in Iran resulted in the generation of a database of 158 data points, each pertaining to a public school building with a framed structure. The generated database includes the information on the seismic retrofit cost values reflected in construction tender documents, together with the information on 14 variables envisaged to have a degree of influence on this cost. This information for a given building was carefully elicited from the final enacted documents developed through the seismic retrofit study of that particular school. Construction costs include structural costs and the costs of architecture and finishes. The database could be of value to those attempting to determine key variables that influence retrofit cost, or to those comparing retrofit practices and costs in different areas of the world.
