Influence of bending deflection rate on properties of fibrous mortar

HBRC Journal, 2013
Selection of the construction materials is affected by many factors including their properties under the applied loads. Loading rate is considered as a very important parameter which influences the behavior of the materials.

Static Modeling of Sagging Cables with Flexural Rigidity and Shear Forces [PDF]

, 2018
Cables are considered perfectly flexible in the classic model-ing without flexural rigidity and with purely tangential cable forces. In this paper, a static modeling of cables is presented where flexural rigidity and shear forces are considered. The calculation details are presented with and without considering the axial extensibility of cables for ...

Seismic performance of short concrete columns reinforced with steel-FRP composite bars and GFRP stirrups

Case Studies in Construction Materials
The steel-FRP composite bar (SFCB) is an ideal reinforcement choice for structures aimed at enhancing durability and resilience. However, research on the seismic applications of SFCBs has primarily focused on flexure-dominated concrete columns, with ...

A novel bridge-type compliant displacement amplification mechanism under compound loads based on the topology optimisation of flexure hinge and its application in micro-force sensing

Smart materials and structures (Print), 2023
The design and modelling of bridge-type compliant displacement amplification mechanisms (CDAMs) are key components in precision engineering. In this study, a bridge-type CDAM under compound loads with an optimum flexure hinge configuration is designed ...

A redundantly actuated 2-DOF 3RRR PKM with flexure joints: less is more

Multibody system dynamics, 2023
The development of a planar manipulator with flexure joints and redundant actuation has been considered before, showing that the redundancy can be exploited to increase the support stiffness and to reduce static actuator loads.
