The beam shown below is subjected to a factored uniform load of 8 kips/ft. The concrete strength is 4,000 psi and the steel is Grade 60. Calculate the nominal shear strength of the beam section. Is the beam safe in terms of the shear design? If so, redesign the beam to make the design more economical. If not, redesign the beam for shear to make the design safe. 24" an 20 ft 24" 8#9 16" d=21" #3 stirrups @ 10" (center-to-center)

Material Properties

Construction in civil engineering demands high strength, durability, and longevity. These targets can be achieved by better design and analysis, along with the correct choice of materials. Different materials have different properties and hence, they respond and performs differently under the various condition of external loadings. It is therefore a critical task of an engineer to select the right material based on the property that the material is supposed to function in real-time. When speaking about the property, there are different categories of material properties like chemical property, physical property, mechanical property, electrical property, magnetic property, thermal property, etc. These material properties form the basis of material selection in various applications.
