1. Model the truss below in SAP2000. Give all members a cross-sectional area of 2.0 in-and i = 35 in*. Use the steel material (E = 29,000 ksi). Find all of the bar forces and report them in a table. Now change the cross-sectional area of all bars to A 3.0 in2. What change, if any, occurs in the bar forces of this statically determinate truss? 30 k 60k C 60 kT 20 k 18 ft 18 ft

326 СНАРТER 6 BENDING EXAMPLE 6.18 The reinforced concrete beam has the cross-sectional area shown in Fig. 6-39a. If it is subjected to a bending moment of M = 60 kip ft determine the normal stress in each of the steel reinforcing rods and the maximum normal stress in the concrete. Take Est = 29(10) ksi and Econc = 3.6(103) ksi SOLUTION Since the beam is made of concrete, in the following analysis we will neglect its strength in supporting...
