Steel Angle Lintel Design

Rating:

Description


This worksheet is used for the design of laterally unsupported steel angle lintels subject to vertical loads. The lintel design loads are specified by the user along with dead load and live load deflection criteria. A single angle or double angle lintel configuration (or both types) may be selected along with user defined limits on the upper and lower bounds of both the horizontal and vertical leg sizes.

Based upon the selected criteria up to 20 selections are automatically made from the AISC database of steel angles. The selections are then presented and sorted in ascending weight order along with the corresponding deflections, allowable bending stresses, and a unity check on the ratio of actual to allowable bending moment. The design can be done with either the ASD or LRFD method of design in accordance with AISC 13th Edition.

This sheet provides a solution to the more complicated issue of the (two principle axis) bending of unequal leg angles and provides a calculation for vertical deflections of such angles which will typically exceed the deflections which are calculated using the geometric moment of inertia.

I have experienced the same problem. What is it I am not doing or what has to be set in the file to correct the problem. I have emailed a PDF printout to John. Thanks Denis

I took a look at this and could not reproduce any #N/A errors. Could you tell me how to reproduce the error so I can see for myself?

After entering all data exactly like the example, program gives me #N/A in all lintel summary fields. what's the magic word or key?

I have a similar program that I use. Nice work!

Thanks for another very usefulcalculation Steve. [Admin]
