Un cable está cargado por medio de una carga uniforme. This causes the deformed shape in the form of the circular segment. Determine the equilibrium force of the cable to obtain the given sag of the cable. The add-on module RF-FORM-FINDING is used for this purpose. Elastic deformations are neglected both in RF-FORM-FINDING and in the analytical solution; self-weight is also neglected in this example.
Se selecciona una barra en forma de W de ASTM A992 para soportar una carga muerta de 30.000 kips y una carga viva de 90.000 kips en tracción. Verify the member strength using both LRFD and ASD.
Consider an ASTM A992 W 18×50 beam forspan and uniform dead and live loads as shown in Figure 1. La barra está limitada a un canto nominal máximo de 18 pulgadas. The live load deflection is limited to L/360. The beam is simply supported and continuously braced. Verify the available flexural strength of the selected beam, based on LRFD and ASD.
En la figura 01 se muestra una viga ASTM A992 W 24×62 con cortante en los extremos de 48.000 y 145.000 kips de las cargas muertas y vivas, respectivamente. Verify the available shear strength of the selected beam, based on LRFD and ASD.
Un cable muy rígido está suspendido entre dos apoyos. Determine the equilibrium shape of the cable (the catenary), consider the gravitational acceleration, and neglect the stiffness of the cable. Verify the position of the cable at the given test points.
Un cable o membrana de acero con pasadores en ambos extremos se carga mediante una carga distribuida. Neglecting its self-weight, determine the maximum deflection of the structure using the large deformation analysis.
Determinar la flecha máxima de un bloque tridimensional fijo en ambos extremos. 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. The block's middle plane is subjected to vertical pressure.
Un voladizo está completamente fijo en el extremo izquierdo y cargado por una fuerza transversal y una fuerza axil en el extremo derecho. The tensile strength is zero and the behavior in the compression remains elastic.
