CR LAURENCE Z-SERIES GLASS CLAMPS (03/27/2014) Page 9 of 19 <br /> Assuming shear strength controls moment: <br /> substituting -H for T and VS for V and solving for H <br /> (1.32-0.37)H=0.18*230#*2 <br /> H= 87# <br /> Mode II failure: <br /> Horizontal load is resisted by couple formed by compression between bottom corner and tension <br /> in screw: <br /> EM=0=H*1.32"+T*0.37" <br /> setting T=TS and solving for H <br /> H= (0.37"*55,1/1*2)/1.32" = 311# Controls strength of force transfer between clamp sections. <br /> Bending strength of piece is same as for leg on main body,will control horizontal load to: <br /> Ha=276# <br /> STAINLESS STEEL Z-CLAMP <br /> For connection to steel strength controlled by clamp body strength: <br /> Ha=276#=maximum allowable horizontal load on clamp. <br /> For connection to wood strength is controlled by lag screw withdrawal: <br /> Refer to page 7 for allowable load. <br /> For connection to concrete strength controlled by anchor strength: <br /> Refer to page 7 for allowable load. <br /> EDWARD C.ROBISON,PE <br /> 10012 Creviston Dr NW <br /> Gig Harbor,WA 98329 <br /> 253-858-0855/Fax 253-858-0856 glrobison@narrows.com <br /> . 3 • <br />
