For the first time in Almaty full passport of apartment stock of multiapartment building was carried out. The structure of the housing stock was revealed with the allocation of groups of buildings according to structural solutions and assessment of their seismic resistance. Based on the results of certification, quantitative estimates of failure probability values for different types of buildings were obtained. Formulas for estimation of quantitative value of seismic risk are obtained. The number of deaths in the estimated zem-shakes was estimated. The results of the assessments will be used for practical recommendations to reduce risk and expected losses in possible earthquakes.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
