12月18日上午,“Maturity Method to Estimate Compressive Strength of Mass Concrete”学术报告会在土木楼212报告厅举行。本期学术报告会主讲人是西弗吉尼亚大学Hung-Liang Chen教授,报告会由门进杰教授主持,金沙国际部分教师及近百名研究生参加了本期报告会。

报告上半场,Chen教授根据收集的温度变化记录,用等效龄期来估算现浇混凝土强度。在施工后第4、28和56天从立方体中取出芯样,并将芯样强度与预测强度进行比较。结果表明,现浇混凝土的预测强度始终高于顶面位置的实际核心强度。

报告下半场,Chen教授先容了玻璃钢聚合物筋(GFRP)的优缺点,并提出利用GFRP替代连续配筋混凝土路面(CRCP)中的普通钢筋。为了检验GFRP作为CRCP强化材料的可行性,在美国西弗吉尼亚州马丁斯堡9号公路上建造了第一个GFRP-CRCP试验段。

报告人先容:

Dr. Hung-Liang (Roger) Chen received his M.S. and Ph.D. in structural engineering from Northwestern University, Evanston, IL, in 1985 and 1988, respectively. He joined West Virginia University in 1989 as an Assistant Professor and was promoted to Associate Professor with Tenure in 1995 and Professor in 2000. He has been involved extensively with research in structural dynamics, nondestructive evaluation (NDE), dynamic soil-structure interaction, and material characterization of concrete, composites, timber, and ceramic materials. He also has ongoing research in mass concrete, self-consolidating concrete, GFRP-reinforced CRCP, and NDE of wellbore cement. Dr. Chen has published more than 150 technical publications and has received over 40 research awards with a total of about 4.7 million dollars as Principal Investigator. He has advised over 45 graduate students, including 11 Ph.D. students. He is active on several technical committees for the American Concrete Institute, the American Society of Civil Engineers, and the American Society for Nondestructive Testing (ASNT). He has received numerous honors and awards for his contributions in teaching and research. Dr. Chen is a Fellow of ASNT.
