Uplift capacity of enlarged base piles in sand

The electronic journal of geotechnical engineering (2012)

Hamed Niroumand Khairul Anuar Kassim Amin Ghafooripour Рамли Назир

Pile foundations, also known as substructure, are used to carry and transfer the load of the structure to the bearing ground located at some depth below ground surface. The main components of the foundation are the pile cap and the piles. Piles are long and slender members which transfer the load through the shallow soil of lower bearing capacity to deeper soil or rock of high bearing capacity. They are also used in normal soil condition to resist uplift forces or in poor soil condition to resist lateral forces. Most of the piles are made from three main types of material which are wood, steel and concrete. Piles are normally driven, drilled or jacked into the ground and connected to pile caps. Based on a few number of laboratory model results many investigators reported the uplift response of piles in cohesionless soil, a review of related previous works shows that not much research has been done to define the uplift capacity in cohesionless soil, a problem that is often encountered in field. The paper observed that the ultimate uplift capacity is dependent on the relative undrained/drained shear strength of cohesionless soil, the depth ratio of embedment and soil thickness ratio. © 2012 ejge.

This article will introduce a new version of the metal deck for building residential flooring with a newly designed cold form U section.This flooring will allow residential structures to be built more quickly while also reducing the necessary thickness of the floor.The level of strength and deflection of this floor will be determined via analysis of a floor bed comprised of cold-formed inverted U sections (IUS) covered by sheathing that is subjected to different loading scenarios.The necessary computational quantities associated with the experiment have been compared to established laboratory values by performing all related and applicable tests.Then, these quantities are compared to different existing flooring techniques to determine the efficacy of this technique.The results show that this flooring technique can be effective and cost-efficient in residential applications.

Hamed Niroumand (Corresponding author) Department of geotechnical engineering, Universiti Teknologi Malaysia, Malaysia E-mail: niroumandh@gmail.com K. A. Kassim, R. Nazir, K. Faizi, R. Hainin Department of geotechnical engineering, Universiti Teknologi Malaysia, Malaysia B. Adhami, A. Ghafooripour Department of civil engineering, Islamic Azad University, Central Tehran Branch, Tehran, Iran H. Moayedi Department of geotechnical engineering, Universiti Putra Malaysia, Malaysia Abstract The behavior of steel pipe during wheel load was studied in this paper by FLAC 3D. A steel pipe is buried at a shallow depth beneath a roadway. An analysis is needed to evaluate the effect of wheel loading on the road surface deflection and pipe deformation. The top of the pipe is 1.5m beneath the road surface. The pipe has an outer diameter of 4m and is 0.12m thick. The pipe excavation is 15m wide and 6m depth. The steel pipe is placed on a 0.4m thick layer of soil backfill, and then soil is compacted around the steel pipe. The wheel load is increased during failure occurs in the soil. Soil backfill behavior has been considered with Mohr-Coulomb Model in analysis. The analysis defines the failure load and the resulting soil and pipe displacement. 1. Introduction Predictability of a structural designs performance is one of many important aims of structural analysis. Elastic analysis of structures requires that very specific conditions at all points within the structure and on its boundary are satisfied. Action and reaction forces must be in equilibrium, deformations of adjacent points within and on the boundaries of a structural element must be compatible, and only appropriate stress-strain laws may be employed. To enhance performance, structures and structural elements are often designed as composites of multiple materials. The buried pipe-soil structural composite requires properly selected and compacted soils surrounding the pipe to reinforce it at a manner that favorably minimizes the pipes bending stress and maximizes ring compression. It is the performance of the pipe-soil composite structure that must be predicted by engineering design. A steel pipe is buried at a shallow depth beneath a roadway. An analysis is required to evaluate the effect of wheel loading on the deformation at the road surface, the deflection and stresses in the pipe. For unburied or unsupported pipes of elastic materials, and for unburied or unsupported pipes of plastic materials, at the instant of load application as shown in Figure 1, the relationship between load and deflection is given by:
