Structure Analysis I

Lecture 13 Cables & Arches Ch.5 in text book

Cables Cables are often used in engineering structure to support and or transmit loads from one member to another

Cables subjected to concentrated loads

Example 1 Determine the tension in cables and what is the dimension h ?

Cables subjected to a Uniform Distributed Load

Analysis Procedure

General Case

Note

Example 2 Determine the tension of the cable at points A, B, C

Example 3 Determine the tension of the cable at points A, B

Arches

Arches Types

Three hinge frame

Example 1 Determine the internal forces at Section D

cos20 93 sin20 86 sin20 93 cos

Example 1 Determine the internal forces at Section D

Group Work 1 Determine the internal forces at B

Group Work 2 Determine the Tension at A & B
