Abstract

Objective. The purpose of the work is to calculate frame buildings with flexible connections and with flexible and switch-off connections, to make recommendations for the use of seismic insulation methods depending on the characteristics of seismic events. Method. Development of an algorithm for calculating frame buildings of a frame structural system with seismic protection in buildings with flexible connections and with flexible and switchable connections Result. A method for calculating frame buildings of a frame structural system with seismic insulation in the form of flexible connections and flexible and switchable connections has been developed. A computer calculation program for seismically insulated and nonseismically insulated frame buildings in the Delphi 5.0 programming environment in the Object Pascal language using the Runge-Kutta numerical method of the 4th order for solving differential equations has been compiled Conclusion. It is determined that the construction of frame buildings with the seismic insulation methods considered in this paper, namely with flexible connections and with flexible connections and disconnecting connections, is not impractical for territories where long-period fluctuations are possible, due to the fact that excessively high deformations occur.

Abstract

Подчеркнута значимость инженерных геофизических и геологических изысканий для массового промышленного и гражданского строительства. Отмечено повышение сейсмостойкости зданий и сооружении за счет применения легких металлических конструкций из перекрестных систем стальных ферм при возведении новых объектов и реконструкции существующих. Для контроля и предотвращения резонансных явлений приведена инженерная методика определения наибольшего периода колебания у поверхностного слоя грунта, а также шести форм собственных колебаний каркасов из перекрестных ферм., The importance of engineering geophysical and geological surveys for mass industrial and civil construction was underlined. Increased seismic resistance of buildings and structures due to the use of light metal structures from the cross systems of steel trusses in the construction of new facilities and reconstruction of existing ones. To control and prevent resonance phenomena, the engineering procedure for determining the longest period of oscillation in the surface layer of the soil, as well as six forms of the natural oscillations of the frameworks from the cross trusses, is given., №5(13) (2019)
