Failure Risk for Frame Buildings by Certification Results: Probability Assessment

Abstract

In many situations, the level of safety is established by following the guidelines set forth in rules or regulations. Engineers are accountable for giving quantitative estimates for different factors, particularly failure cost, when extra information is available, such as the owner's needs. By order of the Akimat of the city of Almaty, within 2017-2018, for the first time, a full certification of the housing stock of apartment buildings was carried out. 1847 multi-story frame buildings of various stories entered into the database. Based on the certification results, for the first time, quantitative estimates of the values of the probability of failure and reliability were obtained for frame buildings of various types. The recurrence of earthquakes is taken into account by the current "Seismic zoning map of the Republic of Kazakhstan." The results of assessments of the values of reliability and failure are used for practical recommendations on reducing the risk and expected losses in case of possible earthquakes. A total reinforcement of frame buildings with a first flexible floor (59 buildings) is proposed. The method of amplification should be determined by special research.
