Dynamic and Static Analysis of Cable Arch Bridge Through Ansys - Engineering Assignment Help

Assignment Task

PROJECT NAME: DYNAMIC AND STATIC ANALYSIS OF CABLE ARCH BRIDGE THROUGH ANSYS

DATAS TO PLOT
Side beam length = 2m each side
Main Arch beam = 6m
No. of cables= 7 cables on each side of the pylons
Height of pylons: 1.2 m
Height of arch : 0.8m
Loads: dynamic loads and dead loads
 

DATA THAT SHOULD BE INCLUDED
The truss arch members, bracing members, towers, side beams, side arch mem- bers and piles are represented as two-node beam elements (BEAM44) with 6 degrees of freedom per node. BEAM44 permits the nodes to be offset from the centroidal axis of the beam. The floor system including deck, cross-girders and stringers are also modeled as the equivalent beam elements (BEAM44). For brevity, all connecting members be- tween substructures, such as rigid arms, bearing and expansion joints, are modeled as two node beam elements (BEAM4) that have three translational degrees of freedom (DOFs) and three rotational DOFs at each node. All hangers, cables and pre-stressed tie bars are modeled as truss elements (LINK10) with 3 DOFs per node. The web plates and gusset plates of the main arches are modeled using four-node shell elements with 6 DOFs per node (SHELL63). Eight-node solid elements with 3 DOFs per node (SOLID45) are used to simulate the abutments, cushion caps and collar beams of the abutment. The diaphragms of the side arch rib are modeled as mass elements with 6 DOFs (MASS21).

The material constants are given as follows.

The elastic modulus of steel is Es = 210GPa, the elastic modulus of zinc plating steel wires Ez = 210GPa, the elastic modulus of concrete C50 Ec = 35 GPa, the den- sity of steel ?s = 7800 kg/m3, the density of concrete ?c = 2500 kg/m3, and the Poisson's ratio of steel and concrete are 0.3 and 0.2, respectively.
