A Practical Design Method for Energy Dissipation Structure Min Chen1, a, Guojing He1,b and Chang Liu2,c 1 School of Civil Engineering and Mechanics, Central South University of Forestry and Technology, Changsha 410004,Hunan,China 2China Construction(Shenzhen) Design International,Shenzhen 518000,China) achenmin2028@163.com, bcegjhe@hotmail.com, clchn2sz@126.com Keywords: energy dissipation, viscous damper, Supplemental Damping ratio, time-history analysis Abstract.
In 2003, Kim [6] proposed a method to determine the required supplemental damping ratio based on target roof displacement which is, however, not so easy to master for most domestic engineers.
The results show that the method is reliable and can provide a reference for structural engineers.

Experimental study on fracture properties of cementitious materials Yu Zhu 1,a , Shilang Xu 1,b 1 State Key Laboratory of Coastal and Offshore Engineering, Dalian University of Technology, Dalian 116024, China a yuzhuxx@yahoo.com.cn, bslxu@dlut.edu.cn Keywords: cementitious materials; initial cracking load; fracture; three-point bending beam Abstract: For micro-fiber reinforced strain-hardening cementitious materials, in addition to the basic characteristics and mechanical properties of fiber and interfacial properties between fiber and matrix, mechanical properties of matrix such as strength and crack resistance are essential parameters for material design, too.
Introduction Concrete is an essential material widely used in civil engineering, however, due to the brittleness and poor crack resistance, the integral failure of concrete structure and durability problem have been major research topics for many years.

Fans have been engineered and manufactured to provide flow capacities comparable to those specified for fixed or mounted stairwell pressurization systems.
The model is public domain software available from the NIST website, making it a frequently used design tool by fire protection engineers.
FDS is specifically designed with fire scenarios in mind and can be readily applied to fire protection engineering applications.
