Emhasis is placed on a discussion grlweap manual the operation of diesel manaul and how that operation is modeled by WEAP. You are commenting using your Twitter account. These predictions, while still of limited reliability, are at least grlweap manual than any other available approach. Equipment selection is usually made on a completely subjective basis, with emphasis placed on the use of driving systems owned by the contractor.

The program is interactive and designed to analyse multilayered soils. The various factors which can influence the accuracy of a wave equation analysis are considered, evaluated and discussed. However, the critical tension stress location will not be at the gage location so the magnitude of maximum tension stresses cannot be readily determined. In this discussion of impact problems, the wave mechanics of both continuous and discrete pile models are illustrated.

In this paper the capbilities of the WEAP program will be compared with other commonly used programs. In this paper a procedure grlweap manual be presented grlwdap determining the maximum tension stress in the pile given measurements at the pile top.

Originally developed by the FHWA. Likins During recent grlweap manual wave analyses, or analyses of the elastic pilewere utilized with increasing frequency for both pile design and construction control. An overview of the concept of LRFD as grleeap to driven piles. If a job must grlweap manual estimated, the contractor will usually depend more on previous experience than on anything mannual by normal subsurface investigations.

You can click here for ordering information. Download the ZIP file into the directory you have created. Contractors tend to limit their work to a particular geographical grlweap manual relying on grlweap manual of a familiar type. We also have a printed manual available for WEAP Several grlweap manual had passed since the TTI Program was developed, so it could be expected that other general improvements could be introduced into the program for all types of harmers.

What is the static bearing capacity of the pile given observations taken during pile driving? In order to take advantage of these measurements, the Federal Highway Administration contracted with the authors grlweap manual o prepare a wave equation program which would accurately model the diesel hammer.

What is the efficiency of the driving system? If grlweap manual occurs on the job and the piles cannot be efficiently advanced, the typical result is quarrels hetween the contractor and the engineer, manuxl cost overruns and litigation. Leave a Grlweap manual Cancel reply Enter your comment here They were developed to answer one or grlweap manual of the following questions: The third volume was prepared to aid the computer operator during the initial stages of program and data file loading.

Beginning with the work of Donnell in the early 20th Century the subsequent analytical and computational research is reviewed in grlweap manual detail. Email gtlweap Address never made public. Consideration of the advantages and disadvantages of the method over ASD are considered.

WEAP: Wave Equation Analysis of Pile Driving, with SPILE, Estimation of Pile Ultimate Capacity

grlweap manual Can the pile be driven given a complete description of pile, soil and hammer properties driveabilty?

This site uses cookies. Early grlweap manual techniques are reviewed briefly up to the development of the resistance strain gage. Axial and Lateral — vulcanhammer. We present here WEAP87, the last freely released version grlweap manual the program. These measurements involving piles driven by all types of hammers have been made for several states including New York. By continuing grlweap manual use this website, you agree to grlweap manual use.

Bearing graph screen from WEAP Grlweap manual an appropriate program, extract the files into the same directory. A recent research project sponsored by the Federal Highway Administration produced a new wave equation computer program for the analysis of pile driving WEAP.

Documentation is not included; the methodology behind it is described in detail in the second volume of the FHWA Soils and Foundations Manual. Skip to content The wave equation has become the standard method for grlweap manual the drivability of piles, along with estimating stresses during driving. It and its successors have since become the most commonly used wave equation program for the analysis of driven piles during driving. The modern era of pile measurements and analysis began in earnest with the research at Case Western Reserve University.

Pile Capacity Programs and Spreadsheet: A summary of the early scientific research that forms the basis of the development of one-dimensional wave mechanics is first summarized. All mathematical models must be calibrated to field conditions in an area. The analyzed piles ranged up to 36 inches in diameter and ft in embedment length grlweap manual had driving blow counts up to BPI.

Grlweap manual for the output graphic most of the output of WEAP87 is either text on the screen or text files. The contents of grlweap manual narrative report deal with background, models and applications of the Wave Equation.

During recent years wave analyses, or analyses of the elastic pilewere utilized with increasing frequency for both pile design and construction control.
