The present invention is a modular structural building system and method consisting of prefabricated, precast, composite reinforced concrete raised floor and steel beam panels with adjustable levelling connection assemblies between panels, supported by columns. The system has the ability to accommodate the use of the floor by construction personnel during the on-site assembly process. The perimeter of the raised floor slab can be provided with ducts for a field installed conventional reinforcement means to create a continuous structural diaphragm for the floor panel.

The present invention relates to a beam-column connection structure and a method for connecting a beam and a column. The beam-column connection structure comprises a precast column, a precast steel reinforced concrete beam and a plurality of fasteners. The precast column has a plurality of tension bars horizontally arranged inside the precast column and has an engagement assembly. One side of the engagement assembly is connected with one end of each of the plurality of tension bars, and the other side of the engagement assembly has a plurality of second holes therein. One end of the precast steel reinforced concrete beam has a plurality of first holes corresponding to the plurality of second holes. The plurality of fasteners are inserted into the plurality of first holes and the plurality of second holes such that the precast steel reinforced concrete beam is fixed to the precast column.

A building system for buildings comprising at least two stories, provided with: a plurality of first portals (3, 3) adapted to be arranged along at least two mutually parallel vertical planes and to be fixed to a base (2); first connecting beams (15) for connecting a first portal (3) and the next first portal (3) arranged along a same vertical plane of said at least two vertical planes; first floor panels (17) adapted to transversely connect together both the first portals (3, 3) arranged along the at least two vertical planes, and the first connecting beams (15) arranged along the at least two vertical planes; a plurality of second portals (40, 40) adapted to be arranged along said at least two vertical planes, each on top of a respective first portal (3, 3); wherein each first portal (3, 3) and each second portal (40, 40) are monolithic and substantially consist of at least two pillars (4) parallel to each other and of a beam (5, 5), arranged transversely on top of the pillars (4), each pillar (4) being provided with a plurality of first connecting bars (9), which are arranged inside each pillar (4), parallel to the longitudinal axis thereof, and extend outwards above the beam (5, 5), and wherein a plurality of anchoring plates (11) is included, each anchoring plate being provided with through holes and constrained to the lower end (7) of a respective pillar, whereby the first connecting bars of the first portals are adapted to be inserted and clamped by clamping means (13) into the through holes of the anchoring plate of the respective second portals.

A connector assembly is used to secure a building panel (e.g., building panel) to a building structural element. The connector assembly can be formed of structural materials to effectively transfer load between the panel and the structural element. The connector assembly can include one or more insulating materials to reduce heat transfer between the panel and the structural element.
