ABSTRACT:
An improved structural framing system and associated method for constructing same wherein a specially configured dissymetric steel beam is horizontally disposed and supported between adjacent vertical columns erected on conventional foundations. The dissymetric beam is fabricated having a compressed, block-like top flange formed opposite a substantially flattened bottom flange and integrally connected thereto by an intermediate web. Standard hollow core sections of precast, prestressed concrete plank spanning perpendicular to the dissymetric beam are disposed on either side of the beam and together assembled thereto so that the web of the beam is disposed centrally between facing edges of the plank sections with the bottom flange of the beam supporting the lower surface of the plank and the top flange substantially aligned with the upper plank surface. Grouting of the assembled beam and plank sections with a high-strength grout mixture provides total encasement of the dissymetric beam and produces a composite action between the beam and plank that significantly increases load capacity of the system.
