r arrangements forcarrying counterweight loads into the main trusses, where the counterweight hangsbetween the trusses, might be more serious. It is suggested that a program of tests of the action of high clamping bolts, usedto connect several thicknesses of plate to a splice or gusset plate located on one side ofthe member, would be of assistance in this matter. The authors feel that it may be possible in present bridges to delay or avoid thesefailures in the future by making careful individual studies for each bridge. Acknowledgment Checking of calculations for the dead load weights of steel trusses and concretecounterweight was done by S. J. Bhatt. Checking of calculations for primary stresses,Williot diagrams, basic equations and of secondary moments for Step 1 was done byJ. A. Ausbeck and R. F. Thurgood. The specimens and specimen holders for the testsshown in Table 2 and Fig. 2i were generously donated by the Wisconsin Bridge andIron Co. 3.\RKA JroceedinKs, Vol. 51, 1950, p. 51.
