Long-term Behaviour of Steel-strip Reinforced Wood Shaving-cement Board Roof Panel

摘要

In order to provide a better understanding of the behaviour of a steel-strip reinforced high-density wood shaving-cement board flexural member, a 3-year long-term loading test was carried out on midsize beams and full-scale ribbed roof panels. The long-term behaviour of the members is presented and explained. The test results indicate that a steel strip has a significant influence on long-term stiffness. It is also shown that the long-term load-carrying capacity of the flexural members is about 0.5 * the short-term load-carrying capacity and the long-term deflection is about 1.6-2.5 * the short-term deflection.
