Abstract:
Experimental results from quasi-static cyclic lateral load tests of three reinforced concrete-exterior wide beam-column-slab subassemblages are presented. The effects of having a significant amount of wide beam flexural steel anchored outside the column core for beams more than three times as wide as columns are investigated, particularly in terms of plastic hinge development and spandrel beam torsion requirements. In addition, wide beam shear behavior and anchorage of column bars through the shallow, wide beams are evaluated using relaxed design provisions. Slab participation in wide beam-column-slab connections is also examined.
