ARCH 2615 ARCH 2615 Practice Prelim 3 (Reinforced concrete columns and T-beams)

Jonathan Ochshorn

Reinforced concrete column design | T-beam design | Distributed loads and moment values for T-beams

Directions: Enter values in yellow fields.

Press "update" button. Solutions will be displayed. (Based on ASD method, AISC Manual of Steel Construction, 14th Edition. More detailed explanations and examples can be found in my text.) There will also be short-answer questions and/or sketches on the prelim, not included in this calculator.

4. Compute distributed loads and design moments (15 points): For the dead load weight, live load, and beam geometry specified, compute the design ("factored") load, w_u = 1.2D + 1.6L, in kips/ft units; the negative design moment value, M_u = w_uL²/11, in in-kip units; and the positive design moment value, M_u = w_uL²/16, in in-kip units. Do not consider live load reduction.

Disclaimer: This calculator is not intended to be used for the design of actual structures, but only for schematic (preliminary) understanding of structural design principles. For the design of an actual structure, a competent professional should be consulted. This is a beta version; please report any strange results!
