In this paper,an experimental study is presented on the punching failure of reinforced concrete slab column connection,which is simply supported at the edges and loaded by TNT group charge explosions.

The column-slab joint keeps the concrete flat plate continuous and set a pallet by increasing the thickness of the slab partially near the column capital,in which steel hoops are placed.

Compressive behavior and ultimate strength of gusset plate contacted with single angle

At the gusset plates of the stiffening steel truss girder of the bridge,both the structural formation and stress conditions are complicated.

It is presented concisely the aftermath of earthquakes,seismic behavior in laboratories and relevant code provisions of bracings and gusset plates in the braced frame system,and conception and method for seismic design of gusset plates for ductile performance.

Design of slab-column connections under combined vertical force and unbalanced moment;

The main failure modes of slab-column connections are flexural failure and punching failure under severe earthquake.

In addition to vertical shear force, slab-column connections also have to transfer unbalanced moment due to combined vertical and lateral forces as a result of wind effect or earthquake excitations.
