Punching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection always vulnerable to critical punching shear; thus, it necessary investigate effect various parameters behavior flat slabs. This work presents an experimental study evaluate level prestressing force and layout strands in terms maximum load, deflection, stiffness, ducti...

The behavior of steel structures subjected to seismic actions depends directly on the connections behavior. There are two current tendencies for ensuring the structural ductility: allowing the formation of plastic hinges in the beams by using reduced beam sections or reduced web sections or by ensuring the plastic hinge formation in the connection by using dissipative elements. This paper prese...

Often unbraced, the stability of steel storage racks may depend solely on the pallet beam to upright connector and on the stiffness of the base plate to floor connection ([1]). This paper presents experimental results from cyclic tests performed on portal beam to upright bolted moment connections intended for cold-formed steel drive-in and drive-through storage racks. In storage racks, portal b...

The estimation of damage in steel tendons is important for evaluating the remaining capacity existing tensioned members. This research focuses on calculating Johnson–Cook (LC) model and parameters high-strength material through quasi-static dynamic uniaxial tests. Finite element analysis used to replicate experimental procedure, image correlation analysis, numerical results accuracy verified. I...
