Design and analysis of beams and girders book
This chapter introduces procedures for the analysis and design of joists, beams, and girders. To help control floor vibration, it is recommended that the plywood sheathing be nailed as well as glued to the floor joists. The floor joists will be connected to the floor girder using face-mounted joist hangers with the top of the joists at the same level as the top of the girders. It is more economical to lay out the joists or beams to span the longer direction of the roofer floor bay with the girders spanning the short direction, since the girders are usually more heavily loaded than the joists or beams. The beam or girder deflection is calculated using engineering mechanics principles and assuming linear elastic material behavior. In designing beams and girders, the first step is to calculate all the loads and load effects, and then the beam size is selected to satisfy the bending, shear, deflection, and bearing stress requirements.
