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. == SYLLABUS == === UNIT I - INTRODUCTION AND CODES- DESIGN BASIS PARAMETERS AND REPORT (3T+6P) === *Indian & International Codes for Reinforced concrete Design, Design loads and detailing of reinforcement, Handbooks for reinforced concrete design, National Building Code 2016, Practical building examples, drawing sizes and scales, Reading Drawings – Architectural & Structural. *Introduction to DBR Parameters - Geometric Parameters, Occupancy Categories, Site location and associated parameters, Design life of structures, Material Specifications - Grade of concrete for vertical and floor elements – Grade of reinforcing steel, Exposure and cover requirements, Fire rating requirements, Load Combinations, Serviceability Requirements, Analysis tools, Design Basis Report, Concept explanation with example buildings. === UNIT II - LOADS & SETTING THE STRUCTURAL SCHEME (3T+6P) === *Introduction, dead loads, superimposed dead loads, Live loads, Wind loads, Wind pressure coefficients, Determining global wind forces and wind velocity, storey forces and base shears.

'''TOTAL: 45 PERIODS''' == CASE STUDIES == ➢Structural analysis, design and detailing of a multi-storey building with load calculation (dead, live, wind and seismic) as per Indian standard codes using ETABS<br> ➢Bill of Quantities preparation of the multi storey building structure.<br> == 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 === 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-<br> ➢'''LO1.:''' Model a 14-storey building for given location and loading conditions such as wind, seismic and combined loads.<br> ➢'''LO2.:''' Prepare a Design Basis Report for a multi storey building considering site parameters, MEP services and functionality.<br> ➢'''LO3.:''' Compute loads including wind and Seismic and selection of vertical and lateral load resisting systems<br>
