STR11 Fixed Arch
| | STR11 | Fixed Arch |
| For studying the
charcteristics of a fixed
arch under various load
conditions. | 
| | Description A hardware module, lecturer guide and student guide. The hardware module fits into a Structures Test Frame (Structures Test Frame not supplied). Various loads are applied by means of masses on hangers placed at set positions along the span of an arched structure. The arch is fixed at both ends. At one end of the arch, a moment arm rests on a load cell. This measures the fixed moment reaction. At the other end a load cell measures the horizontal thrust. The equipment includes leads to connect the load cells to a digital force display (digital force display not supplied). The lecturer guide provides details of the equipment including sample experi-ment results. The student guide describes how to use the equipment and gives experiment procedures. This equipment carries a two-year warranty. Experimental Capabilities - Demonstration of the characteristics of a fixed arch.
- Examination of the relationship between applied loads, horizontal thrust and fixing moment produced from a fixed thus redundant in three degrees) arched structure.
- Comparison of behaviour to simplified theory based on the Secant assumption.
