Parmar. According to Codes: LA CityCBCIBCACI & ACI Retaining Wall on Grade Beam & Caisson. This book is the guidance for the construction of hillside. This book presents subject matter related to the analysis and design of reinforced concrete structural members. The focus is on the design of elements in reinforced concrete buildings where the primary reinforcement is steel reinforcing bars or steel wire reinforcement that is not prestressed.

This book provides an extensive coverage of the design of reinforced concrete structures in accordance with the current Indian code of practice (IS ). As some of the Indian code provisions are outdated, the American code provisions are provided, wherever necessary. Driving and Loading Tests on Six Precast Concrete Piles in Gravel Authors: A.

Bishop, V. Collingridge, T. O'Sullivan Source: Géotechnique, Volume 1, Issue 1, 1 Jun (49–58). Here is a comprehensive guide and reference to assist civil engineers preparing for the Structural Engineer Examination.

It offers pages of text and 70 design problems with complete step-by-step solutions.

Precast concrete piles This technical report covers all aspects of the uses of precast concrete piles - design, manufacture, transport, handling, pitching and driving.

Both reinforced and prestressed concrete piles are dealt with and attention is paid to the use of both plan piles and those with enlarged toes. Precast Concrete Piles are the most common type of deep foundation used, to transmit loads through the upper zones of the poor soil to a depth where the soil is capable of providing adequate support.

The precast concrete pile is a reinforced concrete pile which can be circular, rectangular, square, or octagonal in shape.

Thousands of CP40 piling have been installed nationally as the BEST VALUE design solution for a variety of public and private projects. The CP pile is resistant to decay, marine borer attack and consistently demonstrates reliable strength, while providing marine structures with longer service lives, and lower maintenance/life cycle costs.

The sixth edition of this comprehensive monograph on Prestressed Concrete is updated to meet the basic requirements of undergraduate and postgraduate students of Civil, Structural and Highway Engineering streams and practising structural engineers.

The book incorporates the latest specifcations of the revised Indian, British and American codes, with emphasis on the limit state.

The project involved construction of a conventional circular reinforced concrete pumping station, supported on piles. Pile Foundation. Pile foundations are deep foundations used when the site has a weak shallow bearing strata making it necessary to transfer load to a deeper strata either by friction or end bearing principles.

This paper reviews the results of some previous research studies on reinforced concrete pile caps. Majority of pile caps support only one column, besides only a few piles support the pile caps in.

5 Pile Foundations -General Introduction Pile foundations are used when the underlying soils are incapable of resisting the loads from the structure. The piling is placed in the ground through poor quality materials to bear on competent soils.

The piles are either driven into the ground or holes and filled with reinforced concrete.

Cast-In-Drilled-Hole Piles Description Few terms are as self-descriptive as the one given -In-Drilled-Hole (CIDH) pile. They are simply reinforced concrete piles cast in holes drilled to predetermined elevations.

Much experience has been gained with this pile type because of its extensive use in the construction of bridge structures. While. Pile Cushion. The heads of concrete piles shall be protected with a pile cushion made of plywood. The minimum plywood thickness placed on the pile head prior to driving shall not be less than mm (4 in.).

A new pile cushion shall be provided for each pile. The pile cushion shall be replaced if, during the driving of the pile, the cushion. Concrete Piles Dimensions = 18” x 18” x 33’ f c’ = 4, psi normal weight concrete f y = 60, psi (8 #9 longitudinal reinforcement) 16 inner piles at ft radius 16 outer piles at 22 ft radius.

Piles arranged with center-to-center spacing of at least three pile diameters to avoid group effect. Method of Casting Concrete in Piles. The pile concrete is delivered to site by means of truck mixers. The concrete will be received on site and the delivery ticket will be checked for correctness in accordance with the approved mix design.

The quality checking and testing of the concrete to be carried out by an independent testing agency (I.T.A). Types of Concrete Piles. Concrete piles can be either pre-cast pile, or cast in-situ. Concrete piles are generally reinforced. Pre-cast Concrete Piles. For pre-case piles, the reinforcement brings extra strength to resist bending moment during pile pick up, transportation, vertical loads, and bending moment as a result of lateral loads.

The variety of segment lengths available, along with specialist piling equipment, makes precast piles particularly suited to restricted access and low headroom sites. Mini piles. Precast mini-piles and precast concrete beams can be used for underpinning existing wall foundations to repair and improve the stability of housing and other structures.

(b) Pile Hammers. Concrete piles of mm (20 in.) diameter or width and larger shall be driven by means of air, steam, diesel, or hydraulic hammers, unless otherwise approved. Steel piles shall be driven with air, steam, diesel, or hydraulic hammers. Gravity hammers shall only be used if specifically permitted in the contract or approved in.

Sheet pile quay walls have been constructed in South Africa using both reinforced and prestressed concrete sheet piles of special cross-section.

Figs – show concrete sheet pile wall examples and details of the pile cross-section and pile installation that have traditionally been used in South Africa.

The piles are typically tied together by an in-situ cap at the top, which acts as a. Bored pile foundation or drilled shaft foundation is a commonly used foundation for supporting heavy vertical loads.

It transfers the load to the soil below or rock strata with sufficient bearing capacity and reduces the settlement of the structure. The construction of the bored pile is divided into two phases: the drilling phase and the [ ].

Concrete Precast concrete piles shall be constructed in accordance with the details shown on the Drawings, and of the concrete class, proportions, method of mixing and placing in accordance with the provisions of Section All cement used shall be type 1 and concrete shall contain not less than kg of cement per m3.

For comparison in this article, only nominally reinforced bored piles founded in soil are discussed. Structural Capacity Based on ACI In the U.S., ACI is a commonly used standard for the design of reinforced concrete structures. ACI is primarily an LRFD code, but ASD is also allowed.

Bored piles are known as drilled shafts, drilled. There are a number of additional piles types like belled concrete piles, precast concrete piles, screw / helical steel piles etc but the discussion to choose a suitable pile type is not in the intended scope of this article.

The article is intended to discuss design requirements for straight shaft piles only (both concrete and steel).Fig.

Comparison of Wooden and Concrete Piles. The pile and cap being of the same material, they readily bond together and form a monolithic structure. Reinforced-concrete piles can be driven in almost any soil that a timber pile can penetrate, and they are driven in the same manner as the timber piles.e) Minimum grade of concrete to be used in pile foundations has been revised to M f) Provisions for special use of large diameter bored cast in-situ reinforced cement concrete piles in marine structures have been added.

Bored cast in-situ pile is formed within the ground by excavating or boring a hole within it, with or without.
