OVERVIEW

The course provides key design techniques and practical application aspects from L&T’s decades of expertise in designing structures. The course takes the learner through the typical process in designing reinforced concrete buildings particularly those about 10 storeys tall and less than 50 meters in height. This advanced course provides the experience of designing reinforced concrete buildings as it happens in any design office. The course covers schematic design of gravity and lateral load resisting systems in a reinforcedconcrete building, when to choose a particular system and how to size various components (slabs, beams, columns, shear walls). It also includes calculation of loads and analysis of structure, design and detailing of reinforcement in various components in a hands-on manner.

ATTAINMENT OF LEARNING OUTCOMES STUDENT ASSESSMENT PLAN

1. The conceptualisation and comprehension level of learning outcomes intended through the course is measured through assessments conducted in multiple stages.
2. The understanding of concepts & principles, evolution of practices, codes & guidelines, emerging trends etc. are tested through assessment questions.
3. 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

Preparation of a Design Basis Report for a reinforced concrete building considering site specific parameters and loading due to functionality, computation of wind speed and pressure, seismic parameters, load combinations, grid planning and structural systems.

STUDENT ASSESSMENT 2

Students will have to model a reinforced concrete building in ETABS by identifying regional seismic and wind load from appropriate code provisions and designing typical structural elements for the critical load combination.

SOFTWARE EXPOSURE

Learners are exposed to ETABS software for 40% of course duration for analysis and design of complete RCC building including modelling, specifications, loads and combination of loads. The students can use free student version of this software post completion of the course.

COURSE OUTCOMES

On completion of the course, the students will be able to-
➢LO1.: Model a 14-storey building for given location and loading conditions such as wind, seismic and combined loads.
➢LO2.: Prepare a Design Basis Report for a multi storey building considering site parameters, MEP services and functionality.
➢LO3.: Compute loads including wind and Seismic and selection of vertical and lateral load resisting systems
