Název v původním jazyce

A frame structure with elastically embedded diaphragms for regions with increased seismicity

Popis výsledku v původním jazyce

The article will present the principal results of theoretical analysis of controlling the dynamic characteristics of a multi-storey frame structure composed of precast columns and cross beams, which are mutually interconnected by demountable dry joints and thin-walled diaphragms. The embedded thin-walled precast reinforced concrete diaphragms are connected with the frame structure via discrete connections. The discrete connections are designed using the principle of contact rubber (elastomeric) bearings whose number, distribution and stiffness (particularly shear stiffness) are specified based on the magnitude and intensity of static and dynamic effects. The elastomeric bearings, their dynamic characteristics, number and distribution are the essential factors affecting the nature and intensity of the system’s response to static and dynamic effects. The theoretical analysis based on experimentally identified characteristics of elastomeric bearings and a frame structure segment with an embedded diaphragm with elastomeric bearings has manifested a potential for reaching the required dynamic properties of the structure, damping and response of the structure to dynamic effects. The issues related to the response and resistance of building structures to the effects of dynamic loading are currently a focus of great interest worldwide. The presented design of a structure with controlled response represents an actual solution to the issue of securing the safety of structures in seismic regions.
