Course description and aims

Computational Modeling of Concrete Structures: This course presents in a systematic way the evolution of microplane and lattice-particle model formulations for the simulation of the behavior of quasi-brittle materials, in general, and, more in particular, of aging and deteriorating concrete structures. The addressed topics are of interest to graduate students, post-doctoral associates, researchers, and professional engineers who need to become proficient with the use of modern, effective and versatile constitutive equations for the simulation of strain-softening and damage.

Student learning outcomes

The objective of this course is to introduce graduate and senior undergraduate students to advanced topics on the mechanics of quasi-brittle materials and aging concrete. Students will do this by building on the knowledge gained through all mechanics related courses of the undergraduate curriculum (statics, mechanics of materials, concrete design, etc.). Upon successful completion of the course, students will have an advanced understanding of concrete behavior as well as knowledge of specific modeling theories that can be used for the numerical simulation of concrete structures and other quasi-brittle materials. Having successfully completed this course, students will have the necessary skills to conduct concrete research as well as to solve advanced concrete design problems.
