Bridge Support Structure Mechanical Properties Of The Construction Organization Design

This text mainly study the breeze lotus to carry to the construction process the bridge support pole dint inside the piece and whole stability of influence. First, checked a great deal of button up type steel pipe support model establishment moderate breezes lotus to carry the domestic and international cultural heritage of the aspect, understand the domestic and international scholar in these two research results of realm. After more various result of foundation up and analyzed the characteristic of a button up type steel pipe support node, built up to used for the analysis construction process in the calculation model of the bridge support. Carry to the breeze lotus is after the pulsation breeze carried on the thorough analysis particularly, the etc. effect that built up the breeze calms down to carry the model; And press through a breeze the power table at any time got the breeze to press a variety of curve, then, can get the function at support up of at any time the breeze lotus of the variety carry.(1) The next in order, make use of an analysis software in accordance with the software of BBAS of tin's laboratory development the rightness the bridge support the difference carry on various work condition the bottom of the quiet dint the analysis, the analysis the enunciation two kinds of results with; calculating software mutually, the breeze lotus carries the influence to the support to compare greatly, under general circumstance, can't neglect the influence that the breeze lotus carry.(2) Again, carried on the analysis of the random vibration to the bridge support, result enunciation; When the bridge support takes to establish the height higher, the support a crosses the degree at the same time is also not very strong, so support of from flap the frequency and will change very small, is not very strong with the frequency discrepancy of the pulsation breeze. At this time the motive influence of breeze to the support structure compare greatly.(3) Finally, made use of an analysis software to carried on the motive analysis to the bridge support, then consider the pulsation breeze in a sudden analytical, a motive analysis enunciation that analyzes the software: When the support structure of from flap the frequency to compare greatly, the support is affect by the pulsation breeze opposite smaller.(4) When structure of from flap to compare with hour, frequency, the support is affect by the pulsation breeze if move, should dint etc. the variety compare greatly. However it is in accordance with the consideration after breeze flaps the coefficient of etc. the effect quiet dint calculation result under mostly the circumstance mutually, but should adopt the occurrence that the appropriate measure avoids the resonance.
