Failure mode classification of reinforced concrete column using Fisher methodQI Yong-le(戚永乐)1. 2, HAN Xiao-lei(韩小雷)2, JI Jing(季静)2(1. Guangdong Electric Power Design Institute, China Energy...-based seismic design, an engineer must ?rst find out whether the column is expected to fail in shear before or after ?exural yielding. According to column failure characteristics and failure mode......
Creep failure mode and criterion of Xiangjiaba sandstoneWANG Wei(王伟)1,2, LI Liang-quan(李良权)3, XU Wei-ya(徐卫亚) 1,2, MENG Qing-xiang(孟庆祥) 1,2, LÜ Jun(吕军) 1,2(1. Key Laboratory for Geomechanics... fail in a mix mode consisting of shear failure in a single main plane and tensile failure. Confining pressure can restrict brittle failure and enhance the ductility of sandstone. In the creep tests......
J. Cent. South Univ. Technol. (2009) 16: 0663-0668 DOI: 10.1007/s11771-009-0110-7 Failure mode and strength anisotropic characteristic of stratified rock mass under uniaxial compressive situation... by FLAC3D. The failure mode and anisotropic characteristic of strength for stratified rock mass were analyzed. The analysis results show that the numerical simulation can visually reflect the failure modes......

One is how to define the limit state function really reflecting the mechanical mechanism of the failure mode; another is how... body. c) Overturning. Overturning of the whole monolith or part thereof. This failure mode is not explicitly accounted for in the current guidelines in China. Overstressing in itself is, strictly......

construction. Reliability analysis for the dynamical dam safety should be divided into two phases: failure mode identification and the calculation of the failure probability. Both of them are studied based on the mathematical statistics and structure reliability theory considering two kinds of uncertainty characters (earthquake variability and material randomness). Firstly, failure mode identification......
of many failure subsystems and their influences on each other by using multilevel hierarchical structure model and obtaining the critical subsystems. Finally, failure mode effects and criticality analysis (FMECA) was used to perform a qualitative hazard analysis of critical subsystems, determine the critical failure mode, and clarify the direction of reliability improvement. Through an example......
