This is a temporary foundation for a mobile crane. The load is spread by a grillage of timber beams. I am referring to the bottom layer, in contact with the ground, and have calculated the cantilever distance using simple beam theory. The 16" length is limited by the bending strength of the...
I am trying to design a temporary foundation using 9"x3" timbers in cantilever. The bending capacity of the timbers results in a short member (about 16"), when I use simple bending theory.
Is there a deep beam theory applicable to timber? This should allow a longer cantilever and thus be more...
I am a general civil engineer working for a construction company.
We often use mobile cranes on the sites and my task is to design suitable foundations for the outriggers of the cranes.
Often the ground is layered with for example 2m of firm clay over soft clay. To improve the trafficability and...
