Beam analysis calculators from AccessEngineering
These Excel workbooks (in SI and US units) calculate maximum values, plots and tables of beam deflections, shear, and moments. The external reactions acting on the beam are also calculated. The user specifies beam length, load (concentrated forces, distributed forces, and concentrated moments) values and positions, and elastic modulus, and results appear in clearly labeled output cells, tables, and plots.
