TNO DIANA BV are pleased to announce that Dr Ben Deaton of Simpson Gumpertz & Heger will be joining us online to present this short technical training course.

Beam-column joints constitute a critical component in the load path of reinforced concrete buildings due to their fundamental role in integrating the overall structural system.

Earthquake reconnaissance reports reveal that joint failure has contributed to partial or complete collapse of reinforced concrete buildings designed without consideration for large lateral loads, resulting in significant economic impact and loss of life.

To better understand the vulnerability of such infrastructure, this presentation will demonstrate a methodology for simulating the behaviors known to dominate failure of beam-column joints under bidirectional cyclic load using DIANA.

A rotating smeared crack concrete constitutive model—together with reinforcing bar plasticity and nonlinear bond-slip component models—is systematically validated and used to simulate the response of a series of exterior corner beam-column-slab subassemblies of varying seismic deficiency under simultaneous cyclic bidirectional lateral and cyclic column axial load from the experimental literature.
