A plate girder cross section consists of two flanges, 1 ½ inches × 15 inches, and a 5/16-inch × 66-inch web. A572 Grade 50 steel is used. The span length is 55 feet, the service live load is 2.0 kips/ft, and the dead load is 0.225 kips/ft, including the weight of the girder. Bearing stiffeners are placed at the ends, and intermediate stiffeners are placed at 6-2" and 12'-9" from each end. Does this girder have enough shear strength? a....

A simply supported beam as shown in the figure. The beam section is W18x211. The beam must support its own weight and must carry the following loading: Super-imposed distributed dead load = 0.25 kip/ft Distributed live load = 1 kip/ft Concentrated dead load = 12 kip The beam span L = 26 ft and the distance of the concentrated load from the right support a=6 ft. Consider analy- sis of beam subjected to load combination 1.2 dead + 1.6 live....

A rectangular cross section at a location along a beam in bending is
(a). A rectangular cross section at a location along a beam in bending is acted upon by a bending moment and a shear force. The cross section is \(120 \mathrm{~mm}\) wide, \(300 \mathrm{~mm}\) deep and is orientated such that it is in bending about its major axis of bending. The magnitudes of the bending moment and shear force are \(315 \mathrm{kNm}\) and \(240 \mathrm{kN}\) respectively. Determine the maximum bending and shear stresses on the cross section. Plot the bending and...

Problem 1 Reinforced Concrete T-Flanged Sections (50 pts.) You are required to analyze and design the propped cantilever t-section from HM 4 but for shear only. Draw shear V and moment M diagrams for uniformly distributed load throughout the 30ft span and equally concentrated loads at 10ft and 30ft. Recall that the connection at the left joint N1 is fixed. The connection at 20ft N3 is a roller. The right end node N2 is a free end. Use a concrete...

Problem: A 7 m wide concrete bridge deck (with a span of 9.1 m) is supported by two identical simply supported lightly welded I-beams. The 350 mm thick concrete deck acts as a continuous lateral restraint along the whole length of the beams. The bridge is subjected to a uniformly distributed live load (Q) of 10 kPa. The dead load consists of the self- weight of the I-beams and the concrete deck. If the yield stress of the beams fy...
