Steel Truss Anchorage of Cast-in-Situ Foamed Concrete Wall in Earthquake-Resistant Buildings
The technical specifications of Chinese standards require cast-in-situ foamed concrete nonstructural walls to be anchored by steel ties, structural reinforced cast-in-situ concrete columns, and reinforced cast-in-situ concrete ties to ensure seismic capacity. In most cases, anchorages of this kind cannot satisfy the flexibility requirement, and such technical measures are impractical because they require increased labor, high material consumption, and long treatment time. Considering this dilemma, the authors propose a new anchorage measure. In the proposed measure, the anchorage of a cast-in-situ foamed concrete nonstructural wall is provided by three-dimensional (3D) steel trusses that act as a path to transmit loads. Given the brittleness of foamed concrete, the flexibility of a nonstructural wall made of this material must be provided with correct anchorage. Appropriate flexibility is easily achieved with the 3D steel truss. The 3D steel truss is constructed by welding hot-rolled ribbed bars and cast-in foamed concrete so that bond stress between the ribbed bar and foamed concrete is enhanced.
