Composite floor system utilizing asymmetric H-shaped steel to mitigate the problem of floor height, one of the most serious drawbacks inherent in composite steel structures boasts advantages such as increase in floor area up to 10%, economy in building materials and resources and reduction in wastes. [1] However, before it is commercialized and actually used in the field, studies on the long-span structure of composite floor system having the advantage of reduced floor height should be conducted to define its rapid deformational behavior upon a fire and find ways to secure fire-resistance performance, which was why this study was carried out.

Hybrid Control for Seismological Nonlinear Structures on Liapunov’s Theory Ying Pan1,a Tong Zhao2,b 1College of Mechanical Engineering, Shanghai University of Engineering Science, Shanghai 201620, China 2Mechanical Department, Nanjing University of Technology, Nanjing, 211816, China aap_xjtu@163.com, bzhangtchina@njut.edu.cn Keywords: high-raised buildings; non-linear vibration; hysteretic restoring force; hybrid control; stability Abstract: In this paper, the hybrid control method of earthquake excited high-raised buildings is put forword.
Resilience based column [1] proposed a smooth nonlinear hysteretic restoring force model that is owned by the context (4) Which assume that the damping force is linear, this model can take into account nonlinear material yield due to stiffness or strength of the influence of nonlinear degenerate and sclerosis.
By equation (4), the elastic part The work done by non-negative (10) The work done by the linear viscous damping is non-negative (11) Nonlinear hysteretic part of the work done for (12) Restoring force amplitude constant, according to the actual material characteristics, generally taken to be 1, For the control of the hysteresis curve of constant, often taking less than a positive number; Before yielding stiffness ratio of material yield <1; according to the characteristics of the hysteresis curve model, the equation of the internal variable hysteresis <1, we can see (12) the denominator is positive.
