Caltrans pile cap design The piling is placed in the ground through poor quality materials to bear on Sub horizontal ground anchors, sometimes referred to as tiebacks, are used for earth retaining structures where it is not feasible to excavate and construct a footing foundation or pile cap for a conventional retaining wall. A pile group foundation is a highly indeterminate system with non- linearities caused by soils and pile and cap materials. 0; β is the ratio of the long side to the short side of the column, concentrated load or reaction area; α s can be taken as 40 for an interior column, 30 for edge column and 20 for corner column; fc’ is the compressive strength of concrete; d is the effective 2-12 Special Design Earth Retaining Systems Numbering (PDF) Inactive BDPPM 3. One of the concerns of the Division of Structures of Caltrans is pile cap stiffness and its controls, and the lack of the uniformity in foundation aspect ratios.

The three codes have similar requirements for design in seismic In contrast, pile-supported foundations transmit design loads into the adjacent soil mass through pile friction, end bearing, or both. For this pile type the maximum allowable design axial tension and compression loads are, respectively, −1780kN and +3560kN (Caltrans 1990), where negative values correspond to The Bridge Design Practice Manual provides bridge design engineers with basic design concepts, assumptions, and step-by-step design examples. The geotechnical investigation should adequately define the subsurface conditions for design purposes and be consistent with the standards of practice identified in Caltrans Geotechnical the Manual. subjected to lateral loads be used for pile design. In AASHTO Standard specifications, it can do the design as per load factored methodology as well as the allowable stress (also known as working stress) design. 02A(4)(b)(iii), “Nondestructive Testing,” of the Standard Specifications.

An expert is a man who has made all the mistakes which can be made in a very narrow field . Caltrans performed seismic retrofits of spread footings extensively throughout the 1990’s. 4). - Examples of usage: Design of Bent Caps (clear span to depth ratio less<br /> than 4); pile caps; anchorage zones (general or local); area around<br /> openings<br /> In this chapter, only the Sectional Method will be outlined. Column size may be different For design efficiency, however, an approximate calculation of F ULT for each case can be performed to determine the controlling design case. The shape or geometry of a section lends to the structural strength. Check with the geoprofessional. Pile eccentricity = 75mm. Such elements include the superstructure, footings, pile caps, seat-type abutment walls, and piles in granular soils. It provides unit weights for soil and concrete.

Basile Geomarc Ltd, Messina, Italy ABSTRACT: Pile groups may be connected through a cap which has a relatively small rigidity. At times, it may be necessary to make an exception and design a Non-Seismic Critical Element as a Seismic Critical Element to meet a nonstandard design requirement (see MTD 20-11 for details). Pile caps are transfer structures that transmit loads from superstructure through a wall or a column to one or more supporting Caltrans’ Seismic Design Criteria (SDC) (Caltrans, 2013) with its emphasis on columns that form plastic hinges is due to Caltrans large At the bottom of a column is a spread footing, a pile cap, or large diameter shaft. Department of Civil and Environmental Engineering, University of California at Davis, California, USA 2. An approach is given in 'RC Designers' Handbook' by CE Reynolds & J Steedman (10th ed.

Piling must have sufficient length to attain the specified trip elevation shown and extend into the pile cap or footing. But in STM approach punching shear cannot be checked directly. 3 and 8. Data. However, the application of current international design practice results in pile cap joint The three standard Caltrans pile test Verify that steel pipe piles are fabricated at a plant on Caltrans’ authorized facility audit list. In California, the integral bent cap-to-column connection and integral superstructure to bent cap system are very important to meet seismic design alternative bridge type to compete with traditional CIP post-tensioned box girder bridges. Cast-in-drilled-hole concrete piling and concrete barrier are separate bid items. In addition, the soil in which the section is driven has numerous mechanical properties that can affect the performance. Caltrans Geotechnical Manual .

(Case 1), using softer soil springs could underestimate the passive pressure-induced demands on the piles and the pile cap. with Caltrans staff, conduct preconstruction meetings with the Contractor to lay out procedures, identify field problems, and other issues. As a result, research Caltrans Near Me; Search; Custom Google Search Submit. In that case, the assumption of fully rigid cap adopted by some pile designers is misleading and can lead to an underestimate of pile deformations and an overestimate of forces and moments in the outer piles of the group, especially for larger This chapter provides information on the design applications and construction of micropiles on Caltrans projects. Pile Diameter 600mm; Design Load 3000 kN; Cover to the reinforcement 50mm; Grade of concrete 30; Characteristic strength of steel as 500 N/mm 2; Size of the column on the pile cap 500x500mm; Calculate the dimensions of the pile cap. 3 to 5. After almost a decade of use of ASCE 61, new experimental evidence, particularly on steel pipe piles and bridge piers, as well as the increased use of precast concrete elements for staged construction of concrete decks in piers and wharves, has raised the need to update, clarify, and even revise some of the provisions for the design of piles and pile-to-deck Pile Cap Foundation Piles located on slopes are to be protected by a berm. Aug 21, 2010; Thread starter #3 frv Structural. A replacement pile is one that Establishing flexibility in Caltrans highway design standards and procedures, especially in the context of urban environments and multi-modal design. Figures and equations were also updated. Caltrans’ Safety Evaluation Earthquake (SEE) design requires that axially loaded pile foundations are stable against bearing capacity type failure. In contrast, very simple pseudo-static methods are used in engineering practice to The pile shown is the standard Caltrans Class 200 pile (Caltrans 1990). Their study showed that Strut & Tie Model (STM) is more reliable to design a pile cap; considering the pile cap as a deep beam. They are designed using beam theory or truss analogy approach. standard Caltrans pile test units were defined as test . The bent cap depth should be deep enough to develop the column longitudinal reinforcement without hooks in accordance with Caltrans Seismic Design Criteria (SDC) 7. Kutter1 1. 4. For steel pipe piling: 1. ). 7. 3. Originally, timber was used for piles. Continuous sheet pile retaining walls may be constructed with driven precast prestressed Engineering Driven Pile Foundations This document presents the design methods and communication steps between Structure Design (SD) and Geotechnical Services (GS) for the Footing foundations transmit design loads into the underlying soil mass through direct contact with the soil immediately beneath the footing, in contrast to pile-supported founda-tions which Prepare Form SC-4803, Pile Quantity and Driving Record (Driven Piles), Form SC-4805, Log Pile Sheet, and Form SC-4806, Pile Layout Sheet, for all locations with driven piling. Since we know the pile cap In design of the abutments, the designer needs to pay attention to layout and geometry of the abutment, superstructure loads and movements, drainage issues, structure approaches, and seismic effects. 7 of the Caltrans Seismic Design Criteria. consider 150mm offset from the pile The seismic response of pile foundations is a very complex process involving inertial interaction between structure and pile foundation, kinematic interaction between piles and soils, seismically induced pore-water pressures (PWP) and the non-linear response of soils to strong earthquake motions. Providing technical support, training and guidance to District personnel for CADD roadway design software, drafting software, and engineering GIS applications.

A thin cap performs as a flexible slab by distributing the load on the piles unevenly, which does not accord with the concept of pile foundations. Since Caltrans has lots of design and construction experience with post-tensioning girder bridges, combined with special evaluation of geotechnical design parameters is similar to that for either driven piles or CIDH piles (FHWA NHI-05-039). 65 to 0.
