There is a truss structure, assembly and method of manufacturing a truss with a span L and a beam depth H. The truss having a main part includes a substantially planar top chord with a longitudinal centerline and webs connecting between the top chord and a bottom chord. The top chord is separated from the bottom chord by the webs. There is a top chord node where each web intersects with the centerline of the top chord and a bottom chord node where each web meets the bottom chord. At least two of the top chord nodes coincide with one another along the top chord. In use, the elements of the main part are in compression and the bottom chord includes a tension member.

A method of erecting a multi-storey structure is disclosed. During construction, at least a portion of a perimeter facade of the structure is disposed to extend at least two storeys height beyond an upper work area of the structure and forms at least part of a safety barrier for that work area and wherein in erecting the multi-story structure, at least one further floor of the structure is erected over the upper work area. The further floor forming a respective subsequent upper work area of the structure, and wherein at least a portion of the facade is disposed to extend at least one storey height beyond the uppermost of the subsequent work areas.

The invention relates to a lightweight concrete building structure using pre-stressed lightweight structural beams 46 with a lightweight floor panel (48) spanning between beams (46). In a particular arrangement, the parking system using building structure (10) may be about less than half the weight than traditional parking building structures. In accordance with one arrangement of the particular embodiment of the invention, the building structure comprises floor structures having one or more structural beams, and one of more lightweight panels for attachment to the structural beam, wherein the floor structure is defined by joining together the one or more lightweight structural beams and the one of more lightweight panels. This particular arrangement is particularly useful because it permits defining a floor structure capable of sustaining relative large loads (such as a multitude of vehicles) using lightweight floor panels.

A method and an arrangement for supporting a first floor element at a beam and a beam. The beam is provided with a supporting flange section configured to support the first floor element. The method includes supporting the first floor element on the supporting flange section so that a first space is formed between the first floor element and the beam, providing elongated transverse fittings in the beam, providing transverse reinforcements to extend between the beam and the first floor element. The elongated transverse fitting have a first free end at the first lateral side of the beam, and a first protective element is connected to the first free end of the elongated transverse fitting outside the web section of the beam.

Various embodiments provide a functionally reinforced concrete slab including a concrete substrate having a first substrate area with a first reinforcement level and a second substrate area having a different second reinforcement level. The functionally reinforced concrete slab further includes a concrete substrate reinforcement apparatus enclosed within the concrete substrate. The concrete substrate reinforcement apparatus is positioned based on the first substrate area and the second substrate area to provide a non-uniform reinforcement of the concrete substrate.

An interlocking system of modular units engageable to form vertically and horizontally stable assemblies. The modular units include blocks and modular panels, each having vertical and optional horizontal bores that provide passage for plumbing, electrical wiring, and other connectivity. The modular units may be formed of lightweight cementitious materials, and may find use in assemblies such as walls, floors, ceilings, roofs, and entire building structures.

A multi-level parking garage constructed to be in close proximity to an adjacent building includes two or more levels above ground. Each of the two or more levels has a floor and a ceiling. The multi-level parking garage includes a load-bearing support structure for supporting the two or more levels and a plurality of fire-rated, non-load bearing exterior wall panels. Each of the exterior wall panels are independently and removably mounted to the support structure around at least a portion of a periphery of each of the two or more levels such that the plurality of exterior wall panels extend from the floor of each of the two or more levels to the ceiling of each of the two or more levels.
