中文摘要 | 鋼筋混凝土建築物於地震中常受到程度不一的損害,尤其近年連續遭逢多次大地震,在經濟及安全的考量下,許多建築物係採修復補強的方式改善受到損害的結構,繼續延續建築物的使用;然而國內火災頻傳,這些修復補強後的建築物雖然可應付日常使用的狀況,但如遭受火災時其行為是否仍處於安全情況值得進一步探討。本研究藉由非破壞性超音波試驗(ultrasonic testing)了解受損害之結構物經修復補強前後受溫性質變化,以探討結構物受不同程度高溫延燒並歷經不同延燒時間對修復補強後的混凝土結構物安全性之影響;試驗結果顯示有四點主要結論:(1)鋼板貼片補強施工中經由超音波試驗可了解環氧樹脂粘結層的硬固過程隨著養護時間增加,超音波試驗的音波傳輸速率亦增加而漸趨穩定;(2)粘結層剪力強度隨著試驗溫度增高及加溫延時增加,粘結層剪力強度隨之下降;(3)試體受溫溫度越高而粘結層吸收的能量越多,超音波試驗之音波傳輸速率相對降低,粘結層剪力強度隨之下降。;(4)加溫延時增加而粘結層吸收的能量越多,超音波試驗之音波傳輸速率相對降低,粘結層剪力強度隨之下降。 |
英文摘要 | Nowadays, we lack the advanced study on the repaired and reinforced concrete under high temperature. Although those reinforced buildings can function properly under normal condition, but in case of fire the behaviors of these buildings are not well known. It is urgent needed to investigate further the behaviors and safety of such buildings. This project is intended to study the behaviors of the repaired and reinforced concrete specimens when they are subject to high temperature by tests in order to evaluate the influence of temperature and time of fire spreading on the safety. The experiment adopted the specimens which are commonly used methods in engineering practice presently such as steel plate reinforcement. And then proceed with the following tests such as shear test, ultrasonic test in order to understand the properties at high temperature of the concrete, reinforcement material and the repaired structure respectively. By analyzing the data gained from the above tests, we can figure out the higher of shear strength of the solid adhesive layer, the less of sound-wave transmitting time and the faster of the wave transmitting velocity. The higher of the furnace temperature and the longer of the durations result in the apparent decrease of the shear strength. |
