16 Effect of Global Stiffness Buckling modes: h i y 0 2 h i y 0 2 Out-of-plane buckling In-plane buckling 16
17 Effect of Module Length a Buckling mode with inappropriate module length between lacing members: Local In-plane chord buckling 17
18 Effect of Laced Member Buckling modes with weak laced members: Laced member buckling Torsional buckling 18

28 Advantages of Pipe Strut Design of pipe strut is simpler; lesser chance of making a mistake Smaller diameter pipe strut will not be competitive Larger diameter pipe strut can span longer and/or take higher strut force without any intermediate restraint (i.e. no king post, runner beam or splay; hence, higher productivity) No clear advantage in using higher grade steel because design govern by buckling for long span strut 28
29 How to use Pipe Strut? Hydraulic Jack Free End for manual pre-loading Mast Section Connector Fixed End Automatic hydraulic system 29
30 Example of Free End Type 1 Common specification: Φ800*1450 mm Adjustable range: 0-30 cm 30
31 Example of Free End Type 1 Detachable End 31
32 Example of Free End Type 2 Steel wedge to lock the strut after pre-loading 32
33 Example of Free End Type 3 33
34 Example of Free End Type 3 Typical connection between Free End and Waler Steel pipe Detachable End Hydraulic Jack Steel wedge Filling pile Bolted connection Free End Hydraulic Jack Waler 34
35 Example of Fixed End 900mm Twin Waler 700mm 500mm 300mm 500mm 35
36 Flexible Cone Connectors Twin Waler Stiffener Flexible cone connector 36
37 Flexible Cone Connectors Stiffener 500mm φ 300mm φ 37
38 Connection between Mast Sections Bolted connections and connectors Connector Bolts 38
39 Concluding Remarks Use of laced struts in Singapore is highly developed and efficient because of our many years of experience of MRT construction. For pipe strut to be more competitive and productive, it has to space wider and span longer without any intermediate restraint. This will naturally lead to the use of larger diameter pipe struts. However, pre-loading and connection design will be more challenging. Some clever device for manual or automatic pre-loading and flexible connectors will have to be developed. 39
