Large web openings for service integration in composite floors

Obiettivo

Steel or composite beams with large openings through the webs of the steel sections are commonly used and large service ducts are passed through the openings. The integration of services within the beam depth is important in order to minimise the floor zone in long span construction. The research will include test on composite beams with large rectangular and circular openings in regions of high shear. The tests will evaluate the local bending resistance, and issues such as control of local buckling and the effectiveness of web stiffeners. Design recommendations as well as simplified design tables will be presented for scheme design. Practical issues of fire resistance and service integration of this design guidance will lead to the greater use of long span construction with facility for service integration.
