The usefulness of the given research arises from the reduction of complexity of the complicated dynamic calculations needed to describe a high-speed train travelling along the artificial structures. 展开 关键词: Bridge High-speed traffic Train and bridge interaction Dynamic factor Speed effect ...
This paper describes the measurement program and the results obtained, as well as comparisons wherever possible between the observed values and those obtained from beam theory calculations and bridge code equations. It was found that the measured strains were generally much lower than the design ...
Bridge effect of the C=C, C=N and N=N bonds on the long distance electronic charge transfer of para-substituted stilbenoid compounds. By means of [sup 13]C-NMR spectroscopy and ab initio molecular orbital theory calculations, we have analyzed the bridge effect of the C=C, C=N and N=...
My live load is less than or equal to 100 psf. How do I consider the reduced load factor in the ASCE 7 load combinations? Answer Under the Load Cases, select the Additional Settings tab, and activate the “Live load is less than or equal to 100 psf” option (Image 01). Activate...
Track speed and load restrictions were currently in place, yet, calculations estimated that the bridge lacked strength in certain key components. This paper explores a project wherein an alternative approach using targeted instrumentation to monitor the actual stresses under controlled and random loads ...
2) bridge inner forces due to live loads 桥梁活载内力3) live stress 活载应力 例句>> 4) live load moment 活载力矩5) load inner force 荷载内力 1. Taking the single-column reinforced concrete simply-supported hollow slab bridge as an example, this paper introduces two calculations of ...
• Ableton Live and its audio playback is always on priority No.1! So if you load new effects or 3rd party plug-ins, Ableton Live always keeps playing, while Zwobot can get stuck for some milliseconds. This is a feature, not a bug!• Zwobot will save all dialer/toggle/fx-...
They could load the cars at the mine’s railroad siding, packing the bales so that a hole was left in the center of one of them, big enough for Churchill to crawl inside and survive for the roughly sixteen hours it would take him to reach the border. Clearly surprised by Churchill’s...
The Newell Toll Bridgeis about as small and rickety as you might imagine a bridge built in 1905 would be, although it was rehabbed just 67 years ago! It’s just wide enough for two cars to pass on its metal grate open deck, and pedestrian access is provided by a single run of aging...
aExtreme load calculations are based upon a factor of safety of 5, per the Overhead Specification (Ref 4) This calculation conservativiely assumes the sheave loads are applied directly in the middle of the shaft. 极端装载演算根据安全因子5,每个顶上的规格 (Ref这) 演算conservativiely假设的4 she...
