0104414DendaThis award supports a three-year collaborative research project between Professor Mitsunori Denda of Rutgers University and Professor Julio Florez-Lopez of the University on the Andes in Venezuela. The project will focus on the assessment of damage to reinforced concrete structures subject to strong loading. The research team will carry out analytical, numerical and experimental studies to compare the fracture mechanics and lumped damage mechanics approaches of assessing cracking in reinforced concrete structures. The vulnerability of concrete structures to strong loading, such as that caused by earthquakes, results in significant loss of life and property damage. Potential new approaches to assessing the cracking behavior of reinforced concrete could have far-reaching implications for building safer structures and mitigating against damages from earthquakes. This collaboration brings together the efforts of international laboratories with complementary expertise and research facilities. The project will directly involve U.S. undergraduate and graduate students in the international collaboration.

0104414 Denda该奖项支持罗格斯大学的Mitsunori Denda教授和该大学的Julio Florez-Lopez教授在委内瑞拉的安第斯山脉进行为期三年的合作研究项目。 该项目将侧重于评估承受强荷载的钢筋混凝土结构的损坏情况。 研究小组将进行分析、数值和实验研究，以比较评估钢筋混凝土结构裂缝的断裂力学和集总损伤力学方法。混凝土结构易受强载荷的影响，例如地震造成的载荷，导致重大的生命损失和财产损失。 评估钢筋混凝土开裂行为的潜在新方法可能对建造更安全的结构和减轻地震造成的损害产生深远的影响。 这种合作汇集了具有互补专业知识和研究设施的国际实验室的努力。 该项目将直接涉及美国本科生和研究生的国际合作。
