Based on the shaking table test, seismic responses of main parameters two-span skew bridge were gutted. The finite element model test was established by analysis software OpenSEES. An improved single beam quality distribution proposed. stiffness end twice that actual beam, rather than rigid arm. At same time, mass distributed in way shares half and beams at both ends share half, taking into acc...

The historic Penouta mine in northwest Spain is the focus of efforts to extract tantalum from tin mining waste. This paper describes the characterisation of the tantalum mineralogy of waste material from the deposit. Characterisation was realised using quantitative mineralogy and geochemistry. This paper further identifies other phases of interest and investigates the potential for extraction u...

Walking vibration can cause complaints to building users, especially on timber floor. In previous studies, there is a difference in the human evaluation for same between sensory test result using shaking table and full-scale this study, factor of was investigated, it revealed that deflection due landing foot influences lower rigidity Finally, adding effect, correction method walking presented.

The unpredictability in time of seismic activities and the dependence tectonic movements on a multitude factors challenges specialists to identify most accurate related methods avoid catastrophes associated with hazards. Early warning systems are critical reducing negative effects case an earthquake magnitude above 5 MW. Their precision is all better as they corroborate transmit more informatio...
