Is 2911 a p4?

Broadly, piles transfer axial loads either substantially by friction along its shaft and/or by the end-bearing. The portion relating to load test on piles has been covered in a separate part, namely, IS 2911 (Part 4) : 1984 ‘Code of practice for design and construction of pile foundations: Part 4 Load test on piles’.

Is code for laterally loaded piles?

As per Indian Standards, laterally loaded piles are usually analysed using the method adopted by IS 2911-2010 (Part 1/Section 2).

How a load test for a pile is carried out?

Static pile load testing The test procedure is based on the direct measurement of pile head displacement in response to a physically applied load. The test pile is loaded using a calibrated hydraulic jack that applies the test load to the pile by pushing against a beam placed directly over the test pile.

What is lateral load test?

A field test facility was developed to perform full-scale lateral load tests on single piles, pile groups, and pile caps embedded in natural soil and backfilled with granular soil. The facility was designed specifically for this project to evaluate the lateral resistance provided by pile caps.

What is driven cast in-situ piles?

Driven cast in-situ (DCIS) piles are constructed by driving a closed-ended thick-walled steel casing into the ground and then filling it with concrete. Driven cast in-situ (DCIS) piles are constructed by driving a closed-ended thick-walled steel casing into the ground and then filling it with concrete.

Is 2911 a pile foundation?

UNDER –REAMED PILES : IS 2911 (PART III ) – 1980 (1) UNDER-REAMED PILE : If a short bored pile is provided with one, two or three bulbs, to provide anchorage and / or to increase the bearing load, it is known as the under-reamed pile.

Which is code is used for piling?

Following are the Indian Standard Codes on Pile Foundations: IS 2911 : Part 1 : Sec 1 : 1979 Driven cast in-situ concrete piles. IS 2911 : Part 1 : Sec 2 : 1979 Bored cast-in-situ piles. IS 2911 : Part 1 : Sec 3 : 1979 Driven precast concrete pile.

How many piles should be tested?

The number of piles in the sampling test may not be less than 2% of the total piles and should be no less than 5 piles in routine inspection. If there is any serious problem, the whole pile foundation engineering must be evaluated.

What is lateral load capacity of piles?

In general, at a pile-head deflection of 10 mm, the applied load, , is defined as the design value of lateral bearing capacity of single piles. As a result, the m value used to determine the lateral bearing capacity of single piles can be obtained from the m-Y0 curve.

Which is part 1 sec 4 in is 2911?

(Part 1/Sec 4) was introduced in this part of the standard to cover the provisions of bored precast concrete piles. The portion relating to load test on piles has been covered in a separate part, namely, IS 2911 (Part 4) : 1984 ’Code of practice for design and construction of pile foundations: Part 4 Load test on piles’.

Which is the best version of is 2911?

3 IS 2911 (Part 4) : 2013 for working piles. Separate test piles shall be installed for different type (mode) of loadings (namely, vertical, lateral and pull-out). Initial pile load tests shall preferably be carried out prior to execution of piling job.

What is the purpose of the is 2911 test?

5.2 Routine Test This test is required for one or more of the following purposes: a) Checking the safe load as determined from static analysis [ see IS 2911 (Part 1/Sec 1 to 4), IS 2911 (Part 2) and IS 2911 (Part 3)]; b) Detection of any unusual performance contrary to the findings of the initial test, if already done; and c) Workmanship.
