The Study on Ultimate Strength of Fully Embedded Composite Truss Beam

The fully embedded composite truss beam is developed based on composite member, truss system before composite and beam system after composite. The proper design concept and method of the fully embedded composite truss beam are discussed. A bending test on the fully embedded composite truss beam with span length 25.0m is carried out to investigate the flexural behavior and ultimate strength of the developed structure up to failure. A good agreement between the measured and predicted results are observed.
