YEAR AND SEMESTER: FOURTH YEAR, 7th SEMESTER
FACULTY: ( A&C),
( B&D)
CONTACT DAYS / HOURS: 4 HRS PER WEEK, 16 WEEKS
CREDITS: 2 [3]
SUBJECT OUTLINE
Aims
· To understand the basic principles of structural mechanics so that It forms the basis for study of Structure Systems.
· To understand the structural concept, applications feasibilities, scope and limitations of technologically advanced systems and techniques. (No detailed designs mathematical calculations or derivation of formulae are needed.)
· To prepare the students to use their data/knowledge gained in the subject for practical application in Architecture.
Teaching Method
· The emphasis is given to actual working on materials, making of models and studying their behaviour under forces / loads and how different components of structure combine to cover spaces.
· Groups of four to five students will be formed to study the behavior of a materials/structure and their use and to prepare the report/presentation on the same.The course will be conducted in a manner that students understand the concepts and are then able to stimulate critical thinking, thus to be able to apply these concepts in their project. Power point presentations to discuss/introduce the topic, self research by student to develop class notes.
COURSE LEARNING OUTCOMES (CLO):
Students are expected to have:
· Awareness: of technical knowledge & skills related to structural system. This would be seen in the what, why and how of the research as articulated by the student/s to incorporate structural system in their future design projects.
· Knowledge:of relating essence of science with live examples from industry experimenting with models to understand various structural system through self research and guided research.
· Skills: of developing an ability to yield the structural sustainable solutions to augment architectural designs. Gain ability to prepare a discursive structural presentation and report for an intelligent and critical client.
STUDENTS WILL:-
- Revise all codes related to structural design studied in previous semesters and learn about new codes viz. Is 800,is 456,is 875, sp 7,sp6,sp38,sp16,sp34. They will also learn about new codes meant for high rise buildings, drafted by council on tall buildings and urban habitat.
- Determine structural systems compatible with architectural design and other engineering disciplines.
- Identify structural loadings and other structural design criteria.
- Learn about new age high strength materials and composite materials
- Learn about structural design for high rise buildings
- Learn different types of structural systems for large spans like spaceframes, shells, tensile structures, etc.
- Learn about different systems of load transmission, structural systems for plan and elevation. Earthquake resistant structural design, and designs of structural system for redirection of wind forces
