收縮疊加 的英文怎麼說
中文拼音 [shōusuōdiějiā]
收縮疊加
英文
summation of contraction-
Creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions. in this paper, the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition. the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented. this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design
基於現有的試驗資料，高層及大跨度民用建築的徐變分析只能參照橋梁結構中的徐變系數方法或水工結構中的徐變度方法進行.從徐變系數的定義出發，利用積分中值定理和疊加原理，推導並修正了加載齡期與起算齡期不同時徐變收縮應變增量的表達式，對比了應用徐變系數分析徐變的有限元法和應用徐變度分析徐變的初應變法在效率和精度上的差別，並建議應從概念設計的角度出發，採用徐變度的初應變法來估算徐變對高層及大跨度民用建築的影響Abstract : creep analysis methods of high - rise buildings and large span buildings can only refer to creep coefficient method in bridge engineering or the method of degree of creep in hydraulic construction engineering under the present experiment conditions. in this paper, the incremental expressions of concrete creep and shrinkage strain when the initial computational age is not the same as the loading age are derived and corrected from the concept of concrete creep coefficient and the mean value theorem of integral and the principle of superposition. the differences of efficiency and accuracy of creep analysis between the finite element method with creep coefficient and the initial stress method with degree of creep are presented. this paper suggests that engineers should use the initial stress method with degree of creep to estimate the influences of creep on high - rise buildings and large span buildings on the basis of conceptual design

各種收縮變形疊加后，混凝土的限制收縮值超過極限拉伸率導致裂縫的產生。Based on the object - oriented technique, this study defines four types of geographical event, i. e. expansivity, contraction, rebirth and vanishment events for management of land use data. and it further designed an object - superposition data updating model based on the land use feature of point, line and polygon ， which would take the advantage of the gis overlay function to effectly implement of updating spatial and attribute data
從面向對象的方法入手，定義了引起土地利用變化的擴展、收縮、新生與消亡四種地理事件，並分別按點狀地物、線狀地物和面狀圖斑的土地利用實體特徵設計了對象疊加更新模型，從而能利用gis強大的空間分析能力，來有效地實現空間數據和屬性數據的一致性更新。分享友人
