Design Of Raft Foundation Nptel Pdf. The design of raft foundations from a soil mechanics point of

The design of raft foundations from a soil mechanics point of view is relatively simple and is similar to that of isolated footings. repared. the difference between conventional as well as buoyancy raft. 1 This standard ( Part I ) covers the design of raft foundation based on conventional method ( for rigid foundation ) and simplified methods (flexible foundation ) for Watch on The course covers various types of foundations, required soil investigations, soil parameters, and codes of practice. Methods of analysis, experimental investigations, Depth to width ratio, D/B <= 1 Load transfer through direct soil pressure A satisfactory design of a foundation depends upon the accuracy with which the various soil parameters required forthe design are obtained. Then come to your pile foundations pier or caisson foundations; that mean, your deep foundations pile. To avoid excessive distortion of the structure as a result of variation in the load distribution on the raft. It's free to sign up and bid on jobs. Foundations when at shallow surface Field Engineers can be benefited from this course as the design of foundations under critical conditions (those are not generally covered in UG core foundation engineering course) will be discussed here. So, this covers entire area of the structure and it is used when the allowable soil bearing capacity is very low. Kousik Deb, IIT Kharagpur): Lecture 15 - Design of Raft Foundation. However the following points are to be noted. Foundations when at shallow surface Search for jobs related to Design of raft foundation nptel pdf or hire on the world's largest freelancing marketplace with 24m+ jobs. Sometimes pile can be provided with a pile caps, sometimes pile can be provided with pile raft; that means, cap and pile has been connected monolithically. Design considerations for seismic resistant design of foundations. In this video, I will show you how to manually design a mat (raft) footing for three columns using an Excel sheet considering IS code. An extensive survey of research works devoted to study the geotechnical parameters affecting the Lecture series on Design of Reinforced Concrete Structures by Prof. The columns loads calculation for this raft is also will be shown in f the turbidity area of the columns. Watch video lectures, download transcripts, lecture notes, and reference materials. 1. Soil-structure interaction: modulus of sub-grade The conventional method of design of combined footings and mat foundations is to assume the foundation as infinitely rigid and the contact pressure is assumed to have a planar distribution. Soil - Foundation Interaction (Contd. Design of raft foundationFull descriptionNPTEL - ADVANCED FOUNDATION ENGINEERING-1 Module 5 (Lectures 17 to 19) MAT FOUNDATIONS Topics 17. So, these are the different types of combined footings, first is rectangular combined footing, then Raft foundation can be design using several methods. The course Field Engineers can be benefited from this course as the design of foundations under critical conditions (those are not generally covered in UG core foundation engineering course) will be discussed here. 1 INTRODUCTION Rectangular Advanced Foundation Engineering (Prof. The accuracy of the soil parameters depends upon the accuracy 0. It states that when designing the bottom reinforcement of the raft, the value at the face of the Abstract: ign of Raft foundation in will be shown in details. . SCOPE 1. N. Enhance your NPTEL course learning experience. Final desi end of this report with SAFE Access comprehensive study materials for Foundation Engineering. In this type of raft foundation beams are provided with the flat slabs. . And the load transfer mechanism of The document discusses the design of raft foundations. ) In this paper, an attempt has been made to design a raft foundation based on its geotechnical analysis. 2 Raft foundation is a substructure supporting an arrangement ofcolumns or walls in a row or rows and transmitting the loads to the soil by means of a continuous slab with or without depressions or The use of ra ft foundation tends to reduce the chances of differential settlement and allow increased pressure at foundation level to be transmitted with the Abstract- The design of raft or mat foundation in present time i: e 2018 is discussed. Do like and subscribe to us. For more details on NPTEL visit h the difference between conventional as well as buoyancy raft. Dhang, Department of Civil Engineering, IIT Kharagpur. In situations where a raft foundation alone does not satisfy the design requirements, it may be possible to enhance the performance of the raft by the addition of Week 2 :Shallow Foundations: Safe bearing capacity, differential & total settlements, increase in permissible stress under earthquake loads. The procedure of designing a raft foundation is explained along with its necessity and conditions where it is preferred. Design considerations for foundations: Size and spacing of footings, differential settlement, uplift, ground improvement techniques, corrosion protection 6. In this special project the method used in the design called “the Conventional Rigid Method” and all design steps will be shown in the report.
