Document Summary
Civ100 lecture oct 19 analysis of structures: trusses. Fink truss this structure is commonly used in building wooden houses. All four trusses are joined by different means but they can all rotate as if pins joined the members together. In an example where a rectangle structure is joined by 4 members and 4 pins. Imagine that some weight pressed down on the top and lower left pins of the rectangle structure, what will happen to the structure: the structure will slant to the right slightly in a parallel fashion. The change here is that the diagonal distance between the upper left and lower right will increase in comparison to the diagonal distance prior to the force exertion: this force exertion makes the structure collapsible and unstable. So, the solution would be to place a large bar diagonally to stabilize the structure, essentially making the rectangle into two triangles. Ways to stay at equilibrium in pin-joined trusses.
