Separate factors of safety may be specified by the user for side resistance and for end bearing. The new shaft v5.0 can analyze drilled shafts or grouted piles with diameters smaller than 12 inches. The program analyzes straight as well as belled shafts. The program features a second-generation, windows-based module that combines in a single interface the input of data, the processing of mathematical computations, and the graphical display of information contained in the output file. The new shaft v5.0 extends this option of multiple diameters to drilled shafts socketed into weak rock or gravel. SHAFT allows users to investigate capacities of drilled shafts of different diameters thus helping on the selection of most economical sizing.
#Drilled shaft plaxis 2d manual
This manual was produced under sponsorship and contract from the Federal Highway ***************istration (FHWA) and is distributed by the International Association of Foundation Drilling Contractors. In general, most of the analytical methods used by shaft are based on suggestions from the latest FHWA manual Drilled Shafts: Construction Procedures and Design Methods by L. New criteria for soil response of gravel and weak rock were modeled after papers of recent publication. The analytical methods employed by shaft are based on experimental data obtained from hundreds of well-instrumented load tests of full-sized drilled shafts. An additional simple ************-file, containing the complete output listing, is also computed in every computer run. SHAFT features an approach known as concurrent engineering, where input, processing, and graphical output are performed from a single environment. The program allows for any combination of soil layers to be placed in a layered profile. shaft v5.0 can analyze drilled-shaft response in six types of strata: i) clay - cohesive geomaterial, ii) sand - cohesionless geomaterial, iii) clay-shale, iv) strong rock, v) gravel - cohesionless IGM, and vi) weak rock - cohesive IGM. SHAFT is used to compute the axial capacity and the short-term, load versus settlement curves of drilled shafts in various types of soils.
