Earthquake Performance Analysis

Earthquake Performance Analysis

Seismic performance evaluation studies are carried out in advanced laboratories, taking into account the main shock-aftershock earthquake sequences. These assessments are carried out within the framework of a performance-based earthquake engineering where seismic demand limits are defined according to the earthquake return period.

Earthquake Performance Analysis

Our country is on an important earthquake belt and many destructive earthquakes have occurred. In order to accurately assess the seismic performance of structures and infrastructure, seismic performance assessments describing the probabilistic properties of multivariate engineering parameters caused by large earthquake ground motions as well as aftershock ground motions are performed.

Experts suggest methods for integrating probabilistic performance-based earthquake engineering for seismic design and risk assessment. Analytical methods integrate probabilistic seismic hazard analysis, structural analysis, damage assessment and loss estimation.

In the performance-based seismic risk assessment of buildings, maximum and residual drift rates are taken into account.

The seismic performance of a structure is generally evaluated by the maximum interstory drag ratio. Recent post-earthquake functionality assessment of buildings now shows that the interstory drift rate is an important factor in a building's post-earthquake safety and in the economic feasibility of repair and rebuilding.

The vulnerability of existing buildings to earthquakes due to the use of outdated design codes or poor construction practices during design and construction remains a major concern. Many of these older buildings need further evaluation and improvement to improve the potential economic consequences. Accurate assessment of the potential impact of future devastating earthquakes is essential for effective disaster risk reduction. In addition to ground shaking information such as probabilistic seismic risk analysis, fault rupture process, wave propagation and field effects, a comprehensive determination of the fragility of structures such as structural damage accumulation, seismic loss occurrence and social and economic impact is required. The probable damage and losses of a certain building group due to various seismic events are evaluated by means of probability calculation.
