OVERVIEW
This course provides the practical aspects in design of a small to medium rise steel building starting from the selection of the appropriate structural system based on building functionality, to the design and detailing of its various components. This course covers the assessment of different loads in the building, application of the same in analysis and design software models, various vertical and lateral load-resisting systems and the basis of its selection, integration of various services in the building, design and detailing of elements and connections, etc. This course also covers the different stages in design to execution of steel buildings briefly.

CASE STUDIES
A commercial building with multiple storeys with varying load conditions for each storey. The project work is design of the complete structure given in the case study, from the study of the structural DBR, till the final design output, resulting in a structure satisfying the architectural & structural requirements.
ATTAINMENT OF LEARNING OUTCOMES STUDENT ASSESSMENT PLAN
- The conceptualisation and comprehension level of learning outcomes intended through the course is measured through assessments conducted in multiple stages.
- The understanding of concepts & principles, evolution of practices, codes & guidelines, emerging trends etc. are tested through assessment questions.
- The skill outcome related to design, computation, workflow, report & work plan
preparation, implementation etc. are assessed through assignments. Such assignment questions & answer keys will be shared to the college SPOC for enabling evaluation by respective faculties.
STUDENT ASSESSMENT 1
