Problem #2 A beam having a simple span of 4.2 m. carries a concentrated service live load P at its midspan. The beam is made up of a channel section. Assume that the load is applied through the shear center so that there is no torsional loading. Assume lateral loads are applied at both ends only. Prop. of channel section d = 457.2 mm tr = 15.875 mm Sx = 1141 x 103 mm3 ly = 6.785 x 106 mm4 U = 1.2 DL + 1.6 LL ® Determine the nominal flexural strength of the channel using LRFD. Fy = 248 MPa E = 200000 MPa ® Determine the value of P that can be applied to the beam due to its flexural strength use LRFD. = 26.162 mm Lp = 1.307 L; = 5.341 ® Determine the value of P that can be applied to the beam due to its allowable bending stress using ASD. Cb = 1.32 Zx = 1430 x 103 mm3 Solution: Wt. of channel = 77 kg/m O Nominal flexural strength of channel using LRFD: Lo = 4.2 m 4.2 m

Measuring site work, Excavation and Piling

Bid drawings typically include very little material about the precise requirements of site work operations, measuring site work and excavation work differs from measuring most other works on a construction project. The actual site work conditions are not provided and also the dimensions of the excavations are not known during the pre-construction phase. The precise measurement of the excavation and backfill of the earth material and topsoil is important for a contractor to decide upon the total cost required for the process. All the works should be carried out under OSHA (Occupational Safety and Health Administration) standards to ensure the safety of the workers.
