In the paper, friction energy dissipation is discussed mainly. Using nonlinear spring element and combination element, the finite element model of friction energy dissipating brace frame is established.
By ANSYS finite element program the seismic response of a five-story frame structure with friction dissipating braces is analyzed, and is compared with that of the pure frame structure without brace and the brace frame structure without friction dissipation devices.
As XML becomes the new data standard of the Internet, the paper combines with the Web application architecture, brings up and develops a Web reporting design tool and supporting framework based on XML.
In the third chapter, this paper presents the overall frameworks of enterprise system's integration. The frameworks consist of logical framework named "one C two P three I" framework, circulation chain process framework and supporting framework ofinformation technology based on knowledge management.
The author introduces the composition and properties of steel frame-bracing systems such as central bracing frame,eccentric bracing frame and energy disspation bracing frame, and with comparison points out eccentric bracing frame has fine energy consumption capacity and energy dissipation bracing frame is an ideal lateral force resisting system with greater lateral rigidity.
The experimental modal analysis was performed on a two-story steel braced frame model excited by simulated ambient vibrations and hammer impacts.
Damping characteristics of friction damped braced frame and its effectiveness in the mega-sub controlled structure system
The damping characteristics of one-storey friction damped braced frame (FDBF) are investigated, and the influence of the structural parameters on the energy dissipation and the practical engineering design are discussed.
A diagonally Braced Frame meeting the requirements in Section 14 in which all members of the bracing system are subjected primarily to axial forces.
A diagonally Braced Frame meeting the requirements in Section 13 in which all members of the bracing system are subjected primarily to axial forces.
In addition, the structural investigations allowed two different intra-framework hydrogen bonds to be distinguished that are independent of the extra-framework water distribution and are responsible for the stability of the self-supporting framework.
Their cytoplasm extends multiple processes and composes a supporting framework.
The specification of this selection is presented in detail and the supporting framework is described.
Prostheses of the BIONIKS series have definite advantages over bioprostheses formed on rigid supporting framework.
A basophilic lattice, composed of apparently homogeneous meshes, functions as a supporting framework in the maturing lymphocystis inclusion bodies inPleuronectes.
The problem on calculating the effective length for a column in a braced steel frame it discussed in this paper.An analytical modcl.based on the analysis of basic instability configurations of frameworks,for calculating the effective length of an arbitrary braced frame column is proposed and formulated.For the convenience of practical application,a simplified approach to the estimation of the effective length values of columns employed in rigid-joint steel frames is also presented.
Some conifigurating Patterns, means of energy dissipation and friction materlals of friction dampers are illustrated in this paper. Mechanism of energy dissipation, designmethods and engineering pratice of friction damped braced frames are mainly explicated forengineering design.
