This research investigates the effectiveness of strengthening flat slab to column corner connections by using carbon fibre reinforced polymer (CFRP) sheets.
This paper is on the numerical and experimental study of a reinforced concrete prosthesis for the corner connections of timber frames.
In this paper, the use of post-tensioned tendons as a way to rehabilitate end plate bolted connections with weak end plate or bolts is studied constructing 6 experimental specimens of corner connections under SAC cyclic loading protocol.
Three slab-column specimens, which represent interior, edge, and corner connections, and three isolated column specimens were tested to investigate the axial load transfer in non-slender ultra-high-strength concrete (UHSC, f′c ≈ 200 MPa) columns through normal-strength concrete (NSC, f′c ≈ 50 MPa) slabs.
A sliding corner gusset connection, which is connected to beam and column flanges by bolted end plates, but allows sliding deformations at the frame-gusset interfaces via employment of butyl rubber layers, is proposed to minimize such an interaction.
Although brace-type hysteretic dampers have been widely adopted to mitigate structural damage under severe earthquakes, their performance was often limited by premature rupture of the welded corner gusset connection or its surrounding framing members due to additional frame action.
The study is focussed on the behavior of corner slab column connections with structural steel I- or channel-shaped sections (shearheads) as shear punching reinforcement.
I ducked into alleys and hotel room corners and the connection still sped along nicely.
Red-coloured rear signals are used to denote braking, and cornering lamps, in connection with turning, provide extra illumination in the direction of an intended turn.
Using such the configuration will minimize the damage level on the wall corners and the connection can be repaired/replaced after major damage.
