Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.

A masonry terrace of 65mm thick concrete surface with 35mm thick cement tiles rest on 100mmx 200mmtimber spaced at 250mm on centers acting as simple beam with effective span of 3.8 meters. Weight of woodis7.5Kn/M^3 and masonry to be 18KN/m^3. Ew = 13.8GPa. Given:Allowable stresses for bending = 12 MPaFor shear parallel to the grain = 0.9 MPaDeflection = 1/360 of spana. Determine the uniform load it could support with respect to bending.
A rigid beam ABC is supported at C by a pin support, and at A and B by timber struts AD and BE which are in turn supported by pin supports at D and E respectively (Figure 1). The struts AD and BE are constructed using F11 timber (refer Figure 2) with square cross section 40 mm x 40 mm. A uniformly distributed load of 10 kN/m acting horizontally to the right is applied along the complete length ABC. Under the action of this load, in addition to any changes in the lengths of the struts, the pin support at C settles by 1 mm to the right. Assume that the beam and struts are weightless and that the struts will not buckle. (a) Using equilibrium and compatibility considerations determine the support reactions at C, D and E. Hint: Since the struts AD and BE can transfer only axial force, the reactions at D and E act horizontally (that is, there are no vertical reaction components at D and E). (b) Find the normal stress, normal strain and change in length of strut AD.
