Line Beam Analysis for Static Loads – An exclusive construction program for structural analysis

David Childs has developed Line Beam Analysis for Static Loads, an effective construction program for structural analysis. The software is free to download.

This Proforma measures bending moments and shear forces for loads on a single span or continuous multi-span beam by applying the moment distribution method. Static point or distributed loads as well as settlement at the supports can also be examined.

1. Put in data in the yellow cells only.
2. Put in the Span Length for a single span. Any number of spans is examined up to a heighest of 10. If, any of the 10 spans is not utilized, it will be eliminated when loads are included. (Note: To print-out in excess of 8 spans, orientation of paper should be be set to 'Landscape').
3. Enter Modulus of Elasticity (E) multiplied by the Second Moment of Area (I) for a single span. Relative values of EI are applied when settlement effects are not necessary. As for instance, if the beam contains the identical material and cross section throughout then a value of 1 is to be entered for EI for a single span. If settlement of the supports is taken then real stiffness values of EI (measured in kNm2) should have been entered.

4. Click the "Add Loading" button to enter the loads and choose suitable options from the screens that follow.
5. Click the "Add" button to enter loads span by span by. When all the loads are included, then click the "OK" button to measure bending moments and shears collectively containing moment and shear diagrams.

6. The bending moment and shear are measured for any point on the beam by clicking the "Moment & Shear at a Point" button as soon as the loading is included.
