Analysis of Plane Truss

Problem：
The truss shown in the following figure is made of steel with Young’s modulus 210 Gpa and with cross-sectional area 6 cm2 of each member. Using ANSYS to find out:

1. Forces of supporting points the reaction the points.
2. The displacement of each node, and (3) the stress in each member.

Solution:

Key-points of learning in this problem：

1. Using element LINK1 to solve truss problem. g p
2. Units must be in consistence: length－m , force－N
3. Learning ho to rotate Nodal Coordinate System
4. Learning how to define and list Element Table

Preprocessing:

• Define element types
- Link1
• Set up real constants
- A=6e-4
• Set up material properties p p p
- Ex=210e9 , nuxy=0
• Create finite elements
