Calculates bar lengths for standard bar shapes and produces summaries of lengths and weights for bar types and diameters.
This spreadsheet calculates the secondary effects (bending moments and shear forces) produced by the releasing moment from differential temperature effects on a continuous beam.
The effective span and maximum bearing pressure for a plate girder with no specific bearing is calculated in accordance with BD 56/10 clause 16 and Figure 16. 1A
Influence Line diagrams for bending moments at critical sections in a single or multi-span continuous beam.
Abnormal Load Vehicles, HB Vehicles, BD21 Annex D Vehicles and BD86 STGO Vehicles are analysed as moving loads across a single or multi-span continuous line beam to determine critical bending moments and shear forces.
Calculates bending moments and shear forces for loads on a single span or continuous multi-span beam using the moment distribution method.
The modified MEXE analysis to BD 21/01 and BA 16/97 for single span masonry arch with option for axle lift-off.
A Plane Frame Analysis for bending moments, axial and shears forces in a plane frame structure under point loads, UDL's, linearly varying distributed loads (soil pressures) and moments.
Section properties of a riveted plate girder to BD 56/10 and BS5400-3:2000 with facility to allow for corroded elements.
