Analysis of a transmission tower

Aims and expectations at this course

Our expectation after you study:

1- How to create dimensional and geometrical constraints in Sketch module

2- Drawing a draft sketch, then, converting it to the main sketch, by modifying constraints

3- Simulating cables

4- Applying force based on local coordinate

Consider the planar truss with shape of power tower shown in the Figure. The points S and T are attached to the ground to constrain them in all directions. All cross members like CD and BE are made of cables, which means they are not capable of tolerating compression. Here we are willing to observe stress magnitudes in cables, CJ, HE, KN and IO. The results, then, will be compared with the ones given in reference [1]. The lengths of all members given in the Figure are in meter and their cross-sectional area is 0.15 m2. The material of members is, also, steel with Young’s Modulus of 210 Gpa.
