Panel Load (P). Chapter 7. University of Engineering & Technology, Taxila. 1. Properties of Trusses. . Truss is a frame structure in which all the members have axial forces due to the following facts:. Members are arranged in triangles for stability.. Chapter 7. University of Engineering & Technology, Taxila. 1. Prof Dr Z. A. Siddiqi. LOADS. ON TRUSS ROOF. . All the gravity or vertical loads acting on the building trusses are first calculated in terms of the loads acting per one square meter of the horizontally projected area (plan area) having the units kg/m. Educational . Presentation. Introduction. Building Designers need to specify dead and live loads of both fire sprinkler systems and other load requirements imposed under the model building codes. . Truss Designers are responsible for incorporating the additional load from the fire sprinkler systems into the truss design. . Tacoma Narrows Bridge Collapse. “. Gallopin. . Gertie. ”. I-35 .
