hoop stress
解釋
箍應力-
The cyclo - hoop effect which steel tubular has exert to the concrete shows the character of heterogeneous in the arch rib section, the same to the axial direction. the paper verifies the change of the material poisson ration and the concrete grade will make the cyclo - hoop effect obvious alteration, the change of the cyclo - hoop effect and the stress redistribution of the section produced by the shrinking and creeping of the concrete and the expensive concrete on the section
在鋼管混凝土拱肋斷面上，鋼管對內填混凝土的環箍效應具有非均勻性，在拱軸方向上環箍效應也呈現非均勻性。驗證了材料的橫向變形系數、混凝土標號等參數的變化將引起環箍效應的明顯改變；混凝土的收縮、徐變和膨脹混凝土的應用導致鋼管混凝土的環箍效應發生變化並使截面的應力發生重分佈；並總結了其變化的基本規律。 -
On the contents of two sides abovementined, this paper attempts to do some initial researches from three angles as follows : 1, the analyses of anti - seismic features on longitudinal direction of the aqueduct l ) the seismic longitudinal effects are small. the vibrant characters are decided from the structure integration and rigidness of piers and main arch - ring of the aqueduct, so the following measures should be taken in order to weaken and isolate seismic influence : properly broadening the section sizes and adopting the high class concrete, lowering the height and barycenter of building, setting hoop steel bars so as to increase the plasticity of the concrete which can absorb the seismic energy and prevent the damages due to stress centralization on the linkages and changing place
本文試圖就上述的這兩大方面的內容，從以下三個角度進行了初步研究： 1 、縱槽向抗震性能分析1 ）湯峪河吊桿拱支承結構的縱槽向地震效應較小；吊桿式拱架結構動力特性取決于槽墩和主拱圈的剛度，以及結構的整體性，故適當加大構件截面尺寸或提高砼標號，盡量降低結構的建築高度和重心，在構件連接和變截面處增設梗脅，按照約束混凝土的要求來加強箍筋的配置，增加砼的延性，以克服地震時構件連接和變截面處的應力集中造成的坡壞，並吸收大量的地震能量，從而起到隔震，減震的效果。 -
For the stress analysis of dryers under the line load of supporting rollers, according to hoff theoretical solution of thin cylindrical shell under line loads, mangelsdorf approximate solution is modified on the basis of the calculation analysis for 14 sets dryers " dimension by computer programming with matlab software. the approximate formulas of the second largest hoop stress of the middle section of the shell are derived
針對托輥線壓載荷作用下烘缸的受力分析，本文根據薄壁圓柱殼在線壓載荷作用下的hoff理論解，在運用matlab軟體對14組常用烘缸參數進行編程計算分析的基礎上，對mangelsdorf近似解作了修正，並由最小二乘法導出殼體中部截面環向應力次大值的近似計算式。 -
Based on the problem that temperature difference has the influence on the internal stress of reinforced concrete pool wall which is a easy to be ignored in actual engineering design, the paper comparatively systematically calculates and analyses the engineering that reinforced concrete pool wall produces crevice after being completed in construction by theory and experiment, discusses the effect that the temperature stress has on reinforced concrete pool, at the same time the hoop strengthening, crevice mending and ultimately consolidating three treatment method is put forward in the pool crevice mending
摘要基於在實際工程設計中溫差的大小對鋼筋混凝土水池池壁內應力的影響是個容易被忽視的問題，運用理論和試驗相結合的方法，通過對鋼筋混凝土水池在施工完成後產生裂縫的工程實例進行較為系統的計算、分析，討論了此溫度應力的影響效應。 -
