中文摘要 | 混凝土構件在使用之狀況下,對其安全性的考量,除外加荷重及混凝土 本身之強度外,影響構件產生變形之因素亦值得探討。本文藉由變形理論,針對 混凝土在使用狀況下,其發生變形的原因及機理作進一步之探討。包括:1.瞬時 變形:外力施加後立即產生之變形。2.收縮:由於混凝土中水份損失而發生之變 形。3.潛變:由於長期施加應力而產生之變形,變形量隨時間而改變。 |
英文摘要 | Deformations of concrete under service conditions arise from a number ofdifferent stimuli, for instance applied stress, change of moisture content, andchangesin temperature. The response of the concrete to these stimuli is complex, resulting in reversible, irr-eversible, and time-dependent deformations. Thispaper deals with three main types of deformations:1. Instantaneous deformations that occur when an external stress is First applied. 2. Shrinkage, which occours on loss of moisture from the concrete.3. Creep, which is the time-dependent deformation that occurs on the prolonged application of stress. |
