Improving the design and construction technology of earthquake-resistant supports of buildings and structures on foundation slabs with compensators
The article presents solutions for improving the design of earthquake-resistant supports of buildings and structures on foundation slabs with compensators, arranged, including in conditions of dense construction, increased dynamic loads, in earthquake-prone areas and on soils where large precipitation is possible during operation. The proposed design will reduce the labor and material intensity of work, improve the perception of bending and dynamic loads, there will be opportunities to adjust the height of the upper base plate in order to compensate for the precipitation of the foundation during operation. This is achieved by the fact that in a prestressed shallow foundation formed by an upper base plate, a lower base plate resting on a ground base, between the lower and upper base plates there are hydraulic jacks that are connected to the plates with the help of upper and lower ball bearings embedded in the base plates and stressed by a total force equal to or somewhat greater than the weight the structure under construction, with the help of drainage pipes and a spool-type regulating device. To ensure the rigidity of the structure, the upper support plates are combined with a prefabricated frame structure.
