Stress, strength and strain analysis of the crane truss construction.
Nedělka, Pavel ; Borák, Libor (referee) ; Vrbka, Jan (advisor)
This bachelor thesis deals with stress, strength and strain analysis of the plane crane truss construction. The aim of this work is the calculation of forces for the simple frame with the help of joint equilibrium equations. These forces will be modified by further construction treatment. This treatment turns the simply frame into the hyperstatic system. The obtained values data are the input data for the design of geometry of particular bars. The unknown dimensions will be determined by two strenght limit states. These limits are: limit state of elasticity and limit state of stability. Then we will make the strain analysis. It will determine the displacement in the action of the force, the effect of actual clearance as well as the brace failury effect to the construction safety. Further will be determined the influence of the weight of the construction to the strenght.
