18、er loads suspended from panel points.When joists or girders are to be designed to resist uplift and/or lateral forces, such joists and girders and the forces they must resist must be indicated on the drawings. Also,indicate all proper anchorages and bracing designed to resist those forces, as requir

19、ed.The standard joist tables cannot be used verbatim when the depth of the joist is reduced near the ends to accommodate two-way top chord slopes in excess of 10 mm per meter (l/8 inch per foot).
