ultimate stress test 中文意思是什麼
ultimate stress test
解釋
極限應力試驗-
The static triaxial test of two engineerings shows that the breaking strength of asphalt concrete declines significantly as the temperature rises and the strain increases noticeably when breaking. increase in the asphalt content leads to decrease in tangent modulus and cohesion, but the internal friction angle tends to increase. increasing confining stress results in the augment of the maximum stress and the ultimate value of volumetric strain
兩個實際工程的靜三軸變形與強度試驗表明，隨著溫度升高瀝青混凝土破壞強度明顯降低，破壞時應變明顯加大；瀝青含量的增加會導致切線模量和凝聚力降低，但內摩擦角趨于增加；周圍壓力增大會導致最大應力_ d增大，其體變壓縮極限值也越大。 -
Based on analysis and comparison of existing test data applied to existing ultimate strength prediction models, interfacial stress at the end of plate is deduced. after formulas for calculating the effective moment of inertia for frp - strengthened beams being revised and adjustment coefficient related to nominal main steel reinforcement ratio and curtailment length ratio being put forward, strength prediction formulas of compound beams under plate end debonding failure are established. in analysis of strength of compound beams under intermediate crack induced interfacial debonding failure mode, several bond strengths and their relation are introduced
對于板端剝離破壞，在總結現有承載力模型的基礎上，利用已有試驗數據對各承載力計算公式進行了分析比較，進一步採用分階段分析法，推導了板端界面應力的計算公式，在此基礎上，採用加固復合梁有效慣性矩的修正公式，建立了考慮名義配筋率和板端偏移比影響的板端剝離破壞梁承載力的計算公式；對于跨中受彎裂縫導致的粘結破壞，闡述了常見的幾種粘結強度之間的區別和聯系，並基於拉剪粘結強度，提出了跨中受彎裂縫導致粘結破壞的承載力計算公式，並利用現有試驗結果確定了模型中的一些參數；最後，利用試驗數據對本文建立的兩種粘結破壞承載力計算公式進行了檢驗，結果基本吻合。 -
When the stress acted on concrete specimens exceed 60 % of ultimate compressive strength, the coefficient ( k ) will increase obviously but the largest change is still within the order of 10 - 9 cm / s. the time - dependant characteristic can be expressed by the function k = ( a + ct ) / ( l + bt ). the coefficient k decreased significantly in the first 40 ~ 60 hours of the water permeability test, and the decreasing rate became slow as the time goes on
混凝土的滲透穩定性則表現為滲透系數會隨滲透時間增加而減小，減小的趨勢是起初的40 60小時內下降最快，其後愈來愈平緩，其規律可用公式k = （ a + ct ） （ 1 + bt ）來表示。 -
5 ) based on test results and going by ultimate balance theory, the paper drew anti - shear formula of the wall under eccentric loads, and discussed the main factors which influenced its anti - shear bearing capacity. 6 ) based on plain section assumption, the paper studied the normal section bearing capacity of the wall. stress, strain and deformation computation was combined to establish bearing capacity formulas for the normal section under moment, unaxial loads and axial loads respectively
6 ）以應變平截面假定為基礎，對密肋復合墻體正截面極限承載力進行研究，即將墻體從初始受荷到正截面極限狀態的各階段的應力、內力及變形計算貫通起來，建立了墻體正截面壓彎、拉彎承載力實用計算公式和軸心承載力計算公式。
