An Analytical Solution to Composite Modulus of Foundations Improved by Geosynthetic-encased Granular Columns

Numerical Analysis of Geosynthetic-Encased Stone Columns under Laterally Loads

Out of all methods for ground improvement, stone column became more popular these days due to its simple construction and economic consideration. Installation of stone column especially in loose fine graded soil causes increasing in load bearing capacity and settlement reduction. Encased granular stone columns (EGCs) are commonly subjected to vertical load. However, they may also be subjected t...

Experimental investigation of octagonal partially encased composite columns subject to concentric and eccentric loading

Partially Encased Composite (PEC) column is one of the recent achievements in the field of composite columns. This paper presents a combined experimental and theoretical study on the mechanical performances of six octagonal PEC columns subjected to axial compressive and bending moment loading. The major different between them was the concrete reinforcement details. The parameters studied in the...

Analytical Solution to the Constant Modulus Factorization Problem

Iterative constant modulus algorithms have been used to blindly separate and retrieve interfering constant modulus signals impinging on an antenna array. These algorithms have several well-known but basically unsolved deficiencies. In this paper, we present an algorithm to analytically compute the solution to the underlying constant modulus (CM) factorization problem. With this new approach, it...

An Improved Experimental Test Set-up to Study the Performance of Granular Columns

This paper describes an innovative design of a newly developed large test setup for testing the performance of footings supported on soft clay reinforced with granular columns. This advanced testing method is used to examine the settlement of footings supported on granular columns. Two important features of the equipment are a the axial loading system which allows samples to be consolidated und...
