School of Civil Engineering, (SCE) Semester Offering: August CE72.21 : Structural Dynamics 3(3-0) [Elective course] Rationale: As modern structures are becoming more slender and light, they are also becoming more susceptible to dynamic loadings. Examples of real-life dynamic problems that frequently confront civil engineers include: aerodynamic stability of long-span bridges, earthquake response of multi-story buildings, impact of moving vehicles on highway structures, etc. The traditional engineering solutions to these problems, based on "static force" and "static response", are no longer valid in most cases. Many of these problems have to be tackled by applying knowledge of structural dynamics. Thus, a basic understanding of the dynamic behavior of structures as well as the underlying principles is essential for structural engineers.

Instructor(s): SECTION NAME ADr. Pennung Warnitchai Course StructureSTE delivers three types of courses: basic, advanced and interdisciplinary. Basic courses focus on the specific aspects of structural systems. They are offered in five areas - (a) Analysis and Computations (CE72.1x), (b) Dynamics of Structures (CE72.2x), (c) Mechanics of Structures (CE72.3x), (d) Material Technology (CE72.4x), and (e) Structural Design (CE72.5x). While advanced and interdisciplinary courses (CE72.6x) address new frontiers or the integration of skills in a holistic manner and are designed specifically for doctoral or advanced master's students. Advanced courses provide emerging concepts and techniques in Structural Engineering.In offering opportunity and choice, students can design their own study programs according to their inclinations and future career objectives. In addition to the courses specified below, students, under the guidance of their academic advisors, can select courses from a wide range of electives from other fields/schools as part of an approved study plan.August(First) SemesterCE72.11 Computer Methods of Structural Analysis Elective 3 creditsCE72.21 Structural Dynamics Elective 3 creditsCE72.31 Continuum Mechanics Elective 3 creditsCE72.41 Advanced Concrete Technology Elective 3 creditsCE72.61Nonlinear Finite Element Methods for Solids and Structures Elective 3 creditsCE72.63 Programming Tools in Engineering Elective 3 creditsJanuary(Second) SemesterCE72.12 Finite Element Methods in Engineering Elective 3 creditsCE72.22 Wind and Earthquake Engineering Elective 3 creditsCE72.32 Tall Buildings Elective 3 creditsCE72.42 Experimental Methods in Structural Engineering Elective 3 credits CE72.51 Advanced Steel Structures Elective 3 creditsCE72.52 Advanced Concrete Structures Elective 3 creditsCE72.62Forensic Engineering, Structural Evaluation and Retrofitting of Structures Elective 3 creditsCE72.64 Fiber Reinforced Composite Structures Elective 3 creditsCE72.65 Structural Optimization Elective 3 creditsCE72.90 Advanced Topics in Bridge Engineering Elective 3 creditsCE72.9003Selected Topic: Introduction to Materials Science and EngineeringElective 3 creditsCE72.9004Selected Topic: New Concrete Materials and Special ConcretesElective 3 creditsInter-Semester PeriodInstitute-wide course/English or Computer-based course Elective 2 creditsAugust(Third) SemesterThesis OptionThesis proposal preparation/defense and data/information collection 22 creditsResearch Study OptionCoursework (continued) Elective(s) 12 creditsJanuary(Fourth) SemesterThesis OptionThesis preparation and final thesis report defense continuedResearch Study OptionResearch study preparation and final research report defense CE81.72 : Dynamics of Offshore Structures 3(3-0) Rationale:The objectives are to introduce the fundamental of oceanography, basic fluid mechanics, wave theory, hydrodynamics, naval architecture and structural analysis to meet the needs of offshore engineers involved with either fixed or floating offshore structures.
