Seismic damage mechanism of weak beam-column joint frames [PDF]
Magazine of Civil Engineering, 2022 The use of old building design codes and improper execution of recent seismic design practices resulted in substandard and vulnerable reinforced concrete building stock, the majority of which is built with weak beam-column joint connections (i.e.

Exterior reinforced concrete beam column joint subjected to monotonic loading
Alexandria Engineering Journal, 2018 The joints between beams and columns are crucial zones in a reinforced concrete moment resisting frame. The behaviour of such joints greatly influences the strength and ductility of the overall frame.

Seismic Resistance of RC Corner Eccentric Beam-Column Sub-assemblages [PDF]
Journal of Engineering Research - Egypt, 2022 An experimental investigation studied performance of reinforced concrete (RC) corner beam-column connection (BCC) subjected to cyclic loading. Each BCC consisted of upper, lower column and two beams; one of them was free end (A) while the other was fixed

Architected Load Paths Enable Stiffening and Motion Programming in Soft Pneumatic Actuators. [PDF]
Adv Sci (Weinh)A single MARS template introduces an architected reinforcement strategy for programmable soft pneumatic actuators through internal structural organization and selective beam removal. This monolithic architecture enables deformation reconfiguration from continuous bending to joint‐like articulation and torsional motion, allowing one compliant platform ...
