- Abstract:
- Based on rotational friction hinge damper(RFHD),the dry-connected rotational friction dissipative beam-to-column joint(DRFDBJ)is proposed.Such a joint is expected to feature a good energy-dissipation capacity,adjustable performance as well as concentrated damage.To validate the feasibility and rationality of the DRFDBJ for achieving the expected mechanical performance,two load cases of pseudo-static cyclic experimental tests are carried out.The pre-tension force applied on the surface of the friction pads(Pc),which is a critical parameter of DRFDBJ,is selected as the test variable.The results indicate that the mechanical properties of DRFDBJ are mainly provided and determined by RFHD.Stable strength,stable deformation and energy dissipation capacities are exhibited in the tests.The expected damage-concentration feature of the joint is achieved.The errors between the experimental value and the theoretical value of the joint bending moment strength with two Pc- values are not more than 5%.The strength of DRFDBJ could be adjusted by varying Pc-value,thus laying a foundation for the strength adjustment of DRFDBJ.The results could serve as a reference for relative investigations on dry-connected precast concrete structures and frictional energy dissipation devices.
