The most common form is the warren truss with verticals.
Bending moment in a beam lab report.
Common types of trusses bridge trusses in particular the pratt howe and warren trusses are normally used for spans up to 61 m in length.
What you will do in the lab.
The truss structure consists of members elements that takes only tension or compression and no bending moment in what so ever form.
You will choose one of the strain gages and use the p 3500 strain indicator to measure the strain.
Aim of this experiment is to study the effect of force magnitude on shear forces in a beam.
For larger spans a truss with a polygonal upper cord such as the parker truss is used for some savings in material.
In class wednesday 11 26 08 overview a three dimensional truss is tested under transverse loading and the load deflection characteristics and the internal bar member strains are measured.
Tuesday 11 18 08 laboratory work.
For this purpose two of the four aluminum made trusses namely warren truss and pratt truss are analyzed first experimentally and than theoretically.
The instructions to set up the strain gage are given on the p3500 box.
Introduction the purpose of this lab report is to analyze how accurate the theoretical analyses of different trusses are.
Truss structures lab report experimental procedure 4 results 5 discussion 6 conclusion 7 2 truss structures lab report abstract this experiment involved the creation of a warren truss bridge in an attempt to experimentally validate the mathematical methods commonly used to theoretically evaluate structural stability and integrity.
