The result shows that the requirements and testing methods for flammability of building materials are similar between the United State and Canada, and they mainly are engaged in the test of combustibility and flame spread. In European Union, a new classification system for flammability of building materials was implemented in 2001, which includes two systems; one is for floor coverings and the other for all other building units. In Japan, the interior materials are classified into non-combustible, quasi noncombustible and fire-retardant materials according to Cone Calorimeter method (ISO 5660). China has established a non-combustible test, a three-class classification system for combustible wall and ceiling interior finishing materials and a two-class classification system for combustible floor coverings.

Also the response amplitude will be changed with the initial conditions due to the nonlinear properties of the cables.Taking the bending stiffness, cable sag and cable inclination into consideration, the space vibration control of the cables using the visco-elastic dampers in cable-stayed bridges is investigated by joining the center difference method and the state space strategy. Both the maximum modal damping ration and the optimal damper size are obtained, then the practical suggestions are proposed for the design of the dampers. The space nonlinear vibration equations of the cable-damper system are derived, and anew hybrid method for solving the cable-damper system is presented by combing the Newmark method and Pseudo-force technology. According to the known properties of the cable-damper system, the nonlinear transient responses are analyzed under all kinds of excitations. Based on the transient response, the control effectiveness of the visco-elastic dampers is further demonstrated.
