For beam: find factored loads; compute design moment; compute R; find ρ; compute steel area, As; select reinforcement. Check bar fit for beam and deflection control for both beam and slab. Problem solution Slab design, negative moment 1. Find loads: From Table A-2.2, the live load, L...
It further assumes that the beam remains nearly collimated as it passes through the slab. In this paper, we relax this near-collimation assumption and obtain a modified Fermi-Eyges formula which is significantly more accurate for large beam deflections. The modern interest in this beam problem ...
• Beam Formula Sheet • Strength of Materials • Beam Calculator Constraints and Boundary Conditions For a beam to remain in static equilibrium when external loads are applied to it, the beam must be constrained. Constraints are defined at single points along the beam, and the boundary...

In order to demonstrate the proposed concept of ODSRs, theoretical mode shapes of a 15m long simply supported beam with a constant cross section are plotted in Fig. 2a and 2b using φn(x)=sinnπxL, respectively. Fig. 2(c) and 2(d) show the ODSR calculated for these modes using Eq...
