Measured results indicate that the bend deformation and abruption phenomenon appears very quickly when the "two-bridge-junction" method is adopted in the parallel steelplatebeam.
Two different kinds of failure patterns have been observed and the failure of strengthened beam is attributed to the principal stress at the end of steelplate.
明确加固梁具有两种不同破坏模式，其破坏是由钢板端部的主应力大小决定的。

Prebent combined simple supported beam, combining steelplate with concrete, is a new type beam structure. This paper introduces the basic conception, design and construction of this combined beam.
