In this model,a grid-section model is introduced to determine the sectional tangent stiffness of reinforced concrete beam element and analyze its degeneration process,and three-node friction-sliding tendon elements are employed to analyze the fr.

The rock friction-sliding features in condition of bi-axial loading are experimentally studied with gabbro and granodiorite as examples.

Preliminary research on sliding properties of the wooden floor for gymnasium;

This paper firstly studies the Sliding properties of wooden floor for gymnasium using simple regression orthogonal design method in order to offer scientific basis for the theoretical research and actual application of wooden floor for gymnasium.

In order to forecast and control the friction process,the thermal vibration of interfacial atoms stimulated by the interfacial potential energy field is analyzed,and a calculating model of sliding friction coefficient is established based on the thermal dynamic coupling process.

And a new method for the measurement of magneto damped coefficient of magnetic slide block and sliding friction coefficient of the using material is presented simultaneously.

The formula for calculating the sliding friction coefficient was derived.

In the paper,by using Fourier Series,basic harmonic balancing approximation and optimum numerical iterration,the response computation of a two-degrees-of-freedom dry friction damped vibration absorber system with velocith-dependent variable coefficient of sliding friction under harmonic excitation is discussed.

In the paper,by using equivalent linearization technique,the response computation of a single_degree_of_freedom dry friction damped system with velocity_dependent variable coefficient of sliding friction under harmonic excitation is discussed.
