UHPC超高性能混凝土之介紹與其應用
(Bilingual Lecture) Introduction of Ultra-High Performance Concrete and its Applications
講者:洪崇展 成功大學土木工程學系所 特聘教授
Speaker: Hung, Chung-Chan, Distinguished Professor of NCKU
超高性能混凝土(Ultra-High Performance Concrete,簡稱UHPC)為現今國際間受矚目的一種纖維混凝土材料,其不僅改善了傳統纖維混凝土之低工作性,亦同時具有超高強度、耐磨損、抗衝擊、高韌性、以及裂縫抑制能力。
UHPC有緻密的微觀結構,使氣液體不易滲透,擁有比一般混凝土更傑出之防水與耐久性能。UHPC之超高力學與耐久性能已掀起當代營建材料之浪潮,有利於設計細長比更高之構件,提供更高之結構與建築自由度。此外,UHPC優異之耐久性,可有效減少長期所需之維修,相較一般工法,能減少生命週期中所產生之碳排放量。
UHPC已於國際間應用於橋梁、道路、建築結構、建築外牆、以及結構修復與補強等工程中。此演講內容將涵蓋UHPC之 基礎力學 與 耐久性能、以及其在不同工程領域之 應用,並將著重於耐震結構構件、建築應用、以及結構修復與補強。此外,將介紹近期所開發之簡易分析軟體,可提供工程師進行UHPC於結構耐震補強之分析與設計,包含構件採UHPC包覆補強、磚牆之UHPC噴漿補強、UHPC斜撐、以及UHPC耐震間柱。
為方便留學台灣之外籍生學習,並利於以youtube方式推廣於國際,洪教授將以中英文雙語之方式進行演講。
Ultra-High Performance Concrete (UHPC) is a type of concrete that has become increasingly popular in recent years due to its exceptional strength, durability, and versatility that far surpass those of traditional concrete.
UHPC was developed in the 1990s in France as a response to the need for high-performance materials in infrastructure and military applications. Since then, UHPC has been used in a wide variety of applications, including bridges, pavements, high-rise buildings, and architectural facades, as well as for structural retrofitting and repairs.
Despite its many advantages, UHPC is still a relatively new material, and its use is not yet widespread. This speech provides an introduction to UHPC, discussing its general backgrounds, motivation to develop UHPC, and its applications in various fields of engineering. The talk covers the unique mechanical properties and enhanced durability of UHPC, as well as its applications in structural and architectural engineering, including retrofitting and repairs. The analysis and design of structures retrofitted using UHPC are also discussed in detail. Through this comprehensive discussion, the audience gains a better understanding of the potential of UHPC and its applications in various areas of engineering.
In order to facilitate the study of foreign students studying in Taiwan, and to facilitate international promotion through YouTube, Professor Hung will give the speech in both Chinese and English.
