deflections of all the measuring units directly without any correcting approaches. Principles of the three-point method and displacement measurement of the GECS are introduced in detail. Both static and dynamic experiments have been carried out on a simple beam bridge model‚ which demonstrate that the three-point deflection estimation method using the GECS is effective and offers a reliable way for bridge deflection estimation‚ especially for long-term monitoring. Keywords: three-point method; deflection

Finally‚ the machining programming then been transferred to the laser cutting machine control panel by using diskette. The machine that been used was Helius laser cutting machine‚ Figure3.5‚ with rated power of 3kW and carbon dioxide 〖(CO〗_2) laser beam. Detailed specifications of the laser cutting machine are as in Table 3.4
