Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Tribological characteristics of dispersed-filled composite materials

Izvestiya MGTU MAMI, 2014
The article presents the results of laboratory tests of dispersed-filled composites. Tests on friction and wear were performed using “disk - pad” and “rotating bushing on disk” schemes. There is high compatibility of materials in friction pairs of composite material and steel and their advantages over a pair of bronze and steel in terms of wear and ...
