Learn how to transfer slab loads to beams, including one-way and two-way slabs by longer-to-shorter ratio, half-load distribution, and triangular and trapezoidal load patterns on interior and exterior beams.
Convert trapezoidal slab loads into equivalent beam loads using the f factor for exterior and interior beams, and assess dead and live loads with unit-length density calculations.
Learn to prepare a bar bending schedule for reinforced beams, calculating straight and bent bar lengths, hook extensions, clear cover, tie spacing, and total steel weight.
Explore design examples for singly reinforced rectangular beams and slabs, applying approximate and exact methods, checking deflection, detailing reinforcement with specified bar sizes and spacing.
Explore a detailed full example of reinforced concrete beam design for an office building, covering span layout, slab and wall finishes, and reinforcement criteria using U.S. bars.
Explore how doubly reinforced beams use both tension and compression reinforcement to reduce depth below singly reinforced limits, analyze forces, lever arms, and moment capacity with compression steel and concrete.
Analyzes a doubly reinforced rectangular beam under two concrete strength cases, determines balanced and maximum steel ratios, checks tension vs compression control, and computes the design moment capacity.
Explore designing doubly reinforced concrete beams by calculating maximum moment capacity under tension and compression steel requirements, and adjusting reinforcement to balance the 300×500 section.
Analyze and design T and L concrete beams in monolithic slabs, focusing on neutral axis, flange and web compression, effective depth, reinforcement, and balance of tension under moments.
Analyze capacity of D and L beams through stepwise analysis, determine neutral axis position in the flange, and decide rectangular versus dbm design with example calculations.
Design step and design example outlines step-by-step reinforced concrete beam design, including trial dimensions, effective depth, and steel area. It covers interior simply supported beams and dbm cases.
Explore interior and exterior structural systems in high rise buildings, including frame and tube configurations, shear walls, outriggers, and buttress system concepts, to resist lateral loads and enable taller buildings.
Explore ground improvement techniques to boost soil shear strength, reduce permeability and settlement, including field and dynamic compaction, vibroflotation, preloading, grouting, stone columns, soil nails, and geosynthetics.
Explore how a structural scheme locates columns and beams, uses primary beams and kendry beams to limit spans, and plans expansion joints for thermal and seasonal changes.
The "Design Principles of Concrete Structures" course is designed to provide a comprehensive understanding of the fundamental principles and practices involved in designing concrete structures. It covers various aspects of concrete design, including structural analysis, material properties, and design methodologies. Here is a description of the key topics typically covered in this course:
Lecture -1- Load Transfer from Slabs to Beams
Lecture -2- Bar Bending Schedule
Lecture -3 Design Examples
Lecture -4- Flexural Analysis and Design of Doubly Beams
Lecture -5- Flexural Analysis and Design of T & L Beams
Lecture -6- Flexural Analysis and Design of T & L Beams
Lecture -7- One way slab design
Lecture -8- Two way slab design
How load transfer from slabs to beams is discussed and how bar bending schedule/tables are formed are discussed thoroughly. For 1-way and 2-way slab design, determine the design loads: Identify the dead load (self-weight of the slab and any permanent fixtures) and live load (occupancy and use-specific loads) that the slab will need to support. These loads are typically specified by local building codes or design standards. determine the effective span and effective depth: Calculate the effective span of the slab, which is the distance between the supports along the direction of the primary bending moment is discussed. Further topics are given above The Design Principles of Concrete Structures - II is continuation of Couse Design Principles of Concrete Structures - I. Throughout the course, students have to engage in design side by side with lectures.
