Safety of the design is checked using maximum deflection. The beam is made of timber that has an allowable bending stress of 6.5 MPa and an allowable shear stress of 500 kPa. In this paper equations for calculating the maximum span using maximum bending stress are given. There are other references also who have listed the maximum support span.
'axial' along the axis of the element, 'shear' perpendicular to the element).ĭownload an Excel file to your computer containing the nodal results and elemental results. standards for support span, but the bending stress considered in its calculation is very low (15.9 Mpa). X and Y) as well as the local coordinate system (i.e. The internal reactions are given in terms of the global coordinate system (i.e.Within the table, these nodes are referred to as 'Node 1' and 'Node 2'. Any nodes which do not have constraints will not have external reactions.īelow are the results for each element. External reactions may exist for constrained degrees of freedom. Engineering Civil Engineering Civil Engineering questions and answers calculate the allowable bending moment for a solid rectangular 6in by 16in.
All nodes associated with points are listed first, followed by nodes which were created as part of the meshing process.Certain nodes are associated with points, and for those nodes the number of the associated point is given.Cannot display plot - browser is out of date.īelow are the results for each node.
