Abstract A new system of multiple dynamic strain sensors and accelerometers embedded in test piles provides direct synchronous measurement of force and acceleration at various locations within a pile during high strain dynamic pile testing. This instrumentation system creates an opportunity to explore side and end bearing pile resistance distribution with a higher level of confidence and reliab...

The truss-reinforced half-concrete slab has been widely used in prefabricated construction all over the world. It become most component form China. However, its cost is higher than using conventional method. To improve half floor system, it essential to have a comprehensive understanding of slab’s structural performance complete loading history. Six experimental tests on such slabs were carried...
