Abstract
The work contains the results of a survey of a multi-storey administrative building of unfinished construction with subsequent reconstruction. The data obtained in the calculation of the building using the LIRA 9.6 software package have been verified.
Highlights
Due to the lack of relevant technical regulations in the field of earthquake-resistant construction, the main regulatory document for design is KMK 2.01.03-96 "Construction in seismic regions" [1]
Climatic characteristics of the object: Construction area - Tashkent city, seismicity - 8 points; the estimated seismicity of the site is estimated at 9 points, the capital of construction is class II, the class of durability is class II, the degree of fire resistance is class II, the base soils are taken non-planting with a design resistance R = 20 kPa, the soil category for seismic properties is II, groundwater is non-aggressive to concrete normal permeability on Portland cement, the standard depth of soil freezing is 0.68 m, the depth of seasonal freezing of soils is 0.7 m, groundwater within the site has been opened at a depth of 2.8 m from the earth's surface
Since the main objectives of the study were to evaluate the operation of their own elements of structural systems of multi-storey civil buildings and analyze their stress-strain state, this study did not take into account the effect of the interaction of the building with the foundation soil
Summary
Due to the lack of relevant technical regulations in the field of earthquake-resistant construction, the main regulatory document for design is KMK 2.01.03-96 "Construction in seismic regions" [1]. Methods and approaches to the calculation of buildings and structures for seismic effects are described in the literature [2, 3, 4]. A large number of studies on the rationality of the use of various structural systems of multi-storey civil www.psychologyandeducation.net buildings are aimed, as a rule, at assessing one or several structural parameters (number of floors, area, shape, etc.) and substantiating the optimal limits of their use, without considering the issues of their seismic resistance. In this connection, the assessment of the seismic resistance of various structural systems of multi-storey buildings is becoming increasingly important. The question of choosing the optimality criterion and the research methodology itself remains open
