Theory and design of Structures

👆👆 the spredsheet can handle both types of newel stairs with different support conditions. @theoryanddesignofstructures

Supported by beams projecting from shear wall. Usually newel stairs rising around evevators are supported in this manner. @theoryanddesignofstructures

Supported at exterior boundary @theoryanddesignofstructures

☑️Open newel stair analysis and design excel spreadsheet Based on ES EN 1992-1-1:2015 A spreadsheet for analysis and design of newel stair with two major support conditions is prepared. Try the spreadsheet and if you find any errors please inbox me. @theoryanddesignofstructures

☑️ Torsion Design to ES EN 1992-1-1-2015 The pdf file below is an example design of beam member for torsion. @theoryanddesignofstructures ⬇️

☑️Torsion design "It is instructive to classify torsion into two types. Comparability torsion, which may arise in statically indeterminate situations, is generally insignificant; torsional moments will be shed back into the elements carrying bending moments( at right angles to the element carrying torsion), because torsional stiffnesses are lower than bending stiffnesses. Any torsional cracking will be controlled by shear links. However, equilibrium torsion in statically determinate situations, where torsional resistance is required for static equilibrium, will have significant magnitudes, and has to be designed for.
