Bearing Capacity Experiments and Design Suggestions on New Roof System of Profiled Steel Sheet
Full-scaled bearing capacity experiments are performed on a new type of profiled steel sheet, i.e. HV-380. Experiments are divided into two parts. In the first part, positive uniform loads are applied on test specimens to determine bearing capacity of sheet system under downward load perpendicular to sheet. While negative uniform loads are applied on test specimens to determine bearing capacity of sheet system under upward load perpendicular to sheet in the other part. The experiment result indicates that the capacity under negative uniform loads is less than it under positive uniform loads for same sheet type and configuration, i.e. wind uplift governs the design of the new type of profiled steel sheet; and most failure mode is clip failure. Based on experiment result, wind resistances are derived and applicable regions are suggested.
