Description

ющиес  под предельной нагрузкой - ступенчатые шпонки 5, происходит интенсивное нарастание амплитуд колебаний здани  с соответственным нарастанием перерезывающих усилий в местах соединени  (замоноличивани ) строительных блоков 4. При достижении заданного уровн  амнлитуд колебаний здани  1и соответственно перерезывающих усилий щпонки 5 разрушаютс . За счет этого строительные блоки 4 включаютс  в самосто тельную работу (вместо совместной работы в составе монолитных стен), в результате чего снижаетс  жесткость нижнего этажа. Период собственных колебаний здани  измен етс  и опасность нарастани  резонансных  влений отпадает.under the ultimate load - step pins 5, there is an intensive increase in the amplitudes of the building oscillations with a corresponding increase in the shear forces at the junction (monolithic) of the building blocks 4. When a given level of oscillations of the building 1 is reached and, accordingly, the shear forces of the 5 are destroyed. Due to this, the building blocks 4 are included in independent operation (instead of joint work in the composition of monolithic walls), as a result of which the rigidity of the lower floor is reduced. The period of natural oscillations of a building changes and the danger of an increase in resonance phenomena disappears.

Величины начальной и конечной жесткости здани , а также предельна  прочность ,и деформативность ступенчатых соединительных шнонок выбираютс  на основании расчета.The values of the initial and final stiffness of the building, as well as the ultimate strength, and the deformability of the stepped connecting rods are selected on the basis of the calculation.

Если сейсмическое воздействие имеет спектр с преобладанием низкочастотных колебаний , период собственных колебаний здани  со ступенчатыми соединительными шпонками значительно выше величины преобладающих периодов колебаний грунта. Здесь резонансные  влени  про вл ютс  слабо, инерционные силы, а соответственно, и перерезывающие усили  не превышают расчетных, и шпонки 5 не разрушаютс .If the seismic impact has a spectrum with a predominance of low-frequency oscillations, the period of natural oscillations of a building with stepped connecting keys is significantly higher than the magnitude of the prevailing periods of ground oscillations. Here, the resonant phenomena appear weakly, the inertial forces, and accordingly, the shear forces do not exceed the calculated ones, and the keys 5 are not destroyed.

При низкочастотных колебани х длительность силовых воздействий на шпонки 5 возрастает и они, деформиру сь, в заданных пределах , выполн ют роль амортизирующих и гас щих колебани  устройств.With low-frequency oscillations, the duration of the force effects on the keys 5 increases and they, deforming, within the prescribed limits, act as shock-absorbing and damping oscillations of the devices.

Восстановление соединительных ст)ненчатых шпонок 5, в случае их разрушени , происходит самопроизвольно, под воздействием собственного веса и пластичности асфальто-бетонной композиции.Restoration of the connecting st) non-jagged plugs 5, in case of their destruction, occurs spontaneously, under the influence of its own weight and plasticity of the asphalt-concrete composition.

В районах с повышенной сейсмической активностью восстановление несущей способности ступенчатых соединительных шпонок 5 ускор етс  путем нагрева их электротоком, использу  арматуру 6 в качестве электронагревательных элементов.In areas with increased seismic activity, the recovery of the carrying capacity of the stepped connecting keys 5 is accelerated by heating them with electric current, using the reinforcement 6 as electric heating elements.

Предлагаема  конструкци  сейсмостойкого здани  позвол ет расширить область применени  зданий с переменным перидом собственных колебаний; .сэкономить дорогосто щие железобетонные материалы (используемые ранее дл  нижнего этажа), упростить конструкцию нижнего этажа.The proposed design of a seismic resistant building allows to expand the scope of use of buildings with a variable natural oscillation peride; Save costly reinforced concrete materials (previously used for the lower floor), simplify the design of the lower floor.
