Theoretical and Experimental Research of a Frame Structure with Articulated Joints

Abstract:

Research within the TACR TA02010837 project “A Multi-Purpose Demountable Prefabricated Reinforced Concrete Building System with Controlled Properties of Joints and Potential Repetitive Use” included the design of a prefabricated column system with articulated joints of columns and cross bars and diaphragms elastically embedded in some spans; this system allows the modification of static and dynamic characteristics – stiffness and the load-bearing system’s response to external static and dynamic loading effects and impacts. The article presents partial results of a theoretical and experimental analysis of the behaviour of a frame span with a diaphragm discretely connected by means of rubber bearings and cross bars.
