A truss structure consists of three rods (one steel and two copper) joined by a rigid member. The structure is loaded by a concentrated force and a temperature difference. Determine a flecha total da estrutura, sem considerar o peso próprio.
A timber beam reinforced by two steel plates at the ends is loaded by pressure. The wood fibers are parallel to the upper loaded side of the beam. A superfície plástica é descrita de acordo com a teoria da plasticidade de Tsai-Wu.
A structure made of I-profile trusses is supported on both ends by spring sliding supports and loaded by transversal forces. O peso próprio não é considerado neste exemplo. Determine the deflection of the structure, the bending moment, the normal force in the given test points, and the horizontal deflection of the spring supports.
Determine the maximum deflection of a three-dimensional block fixed at both ends. The block is divided in the middle: the upper half is made of an elastic material and the lower part is made of timber - an elasto-plastic othotropic material with the yield surface described according to the Tsai-Wu plasticity theory. O plano central do bloco está sob pressão vertical.
