1. Both vertical and lateral stiffness are greater than simply supported beams, and the internal force distribution is more reasonable
2.For multi-hole bridges with a span greater than 120m, it is more reasonable to use continuous truss beams. Steel materials can save about 8-10% compared with simply supported beams.
3.Structural layout
The number of spans per joint is two or three spans, rarely more than five spans.
Two-hole continuous beam should be made of equal span.
The reasonable ratio of the span of the three holes is 7:8:7. For the sake of beauty, an equal-span layout is often used.
Beam height: usually 1/7~1/8 of the span, the support can be increased appropriately.
Truss Charactistic
(1)Professional welding technology,beautiful outline and polishing finish
(2)Lightweight but strong loading capacity,durable and firm
(3)Made by aluminum alloy,stable and energy saving
(4)Long span,widely used for different scale of different occasion
(5)Superior raw material,high quality and cheap price
