The single angle and double angle sections [Fig 2(a)] are used in light roof trusses as in industrial buildings. The tension members in bridge trusses are made of channels or I sections, acting individually or built-up [Figs. 2(c) and 2(d)].

Typical shear connections occur as a lap or a butt joint used in the tension members [See Fig. 3]. While the lap joint has a tendency to bend so that the forces tend to become collinear, the butt joint requires cover plates. Since the load acts in
May 26, 2021 · The typical failure mode of a welded single-angle tension member is a gross section failure. The rupture strength of the single angle tension member affected by the effect of shear lag. A full-scale test program on the welded single-angle specimens' rupture strength is reported in this paper. A total of twelve tests was performed on a single-angle specimen with a welded end connection. Bolted Joint Design - Fastenalstretch and/or separate the joint. The tension load, no matter how small, will add to the stress in the bolt and/or partially relieve the joint. The bolts in a tension joint must act like clamps. The tightening of the bolt and nut produces a tensile pre-stress, which is approximately equal to the compressive stress introduced in the joint material.

Chapter 4 CPMPRESSION MEMBER DESIGNBending moments cannot be neglected if they are acting on the member. Members with axial compression and bending moment are called beam-columns. 4.2 COLUMN THEORY Consider a long slender compression member. If an axial load P is applied and increased slowly, it will ultimately reach a value Pcr that will cause buckling of the column.
6.2 -6.3 Trusses Trusses are used commonly in Steel buildings and bridges. All straight members connected together with pin joints connected only at the ends of the members and all external forces (loads & reactions) must be applied only at the joints . Definition:A truss is a structure that consists of Every member of a truss is a 2 force member. Chapter 6a Plane Stress/Strain EquationsThe two-dimensional element is extremely important for:(1) Plane stress analysis, which includes problems such as plates with holes, fillets, or other changes in geometry that are loaded in their plane resulting in local stress concentrations. Plane Stress and Plane Strain Equations The two-dimensional element is extremely important for:
Since the body is rigid, all the particles in the body move through the same displacement, v, so that the virtual work done on all the particles is numerically the same.However, for a pair of adjacent particles, such as A 1 and A 2 in Fig. 15.3, the self-equilibrating forces are in opposite directions, which means that the work done on A 1 is opposite in sign to the work done on A 2.
