The shear strength of a grade 8 bolt is 90,000 psi, assuming the bolt is between 1/4 inch to 1 inch. Shear strength is typically estimated to be 60 percent of tensile strength. The tensile strength of a grade 8 bolt is at least 150,000 psi.
Know MoreAll grade 8 bolts have the same tensile strength per square inch. Thus, the larger the bolt, the stronger the tensile strength of the bolt. Shear strength must be calculated, because the American Society for Testing and Materials does not require shear strength values to be published. To calculate tensile strength of a bolt, the tensile stress area should be multiplied by 150,000 psi.
Learn more about Building MaterialsA grade beam is a long, reinforced concrete beam that transfers the weight of a building to supporting structures as part of the building's foundation. It is called a grade beam because it is built at grade or ground level.
Full Answer >Designing a concrete slab on grade requires the consideration of many different aspects, including determining stationary live loads, thicknesses and many other factors. It is best to consult a professional to determine the exact specifications.
Full Answer >An 8-by-8-by-16-inch concrete block weighs about 28 pounds. These blocks are used for a variety of different projects because they have a high compression strength of 1,800 pounds per square inch. Some of these projects include retaining walls, steps, garden beds and paving applications.
Full Answer >The weight of a sheet of drywall depends on the thickness, brand and type of drywall. A 4-inch by 8-inch sheet of 1/2-inch thick standard drywall weighs approximately 52 pounds. Moisture resistant drywall, or green board, weighs about the same as standard drywall.
