TL;DR: In this article, a numerical example and solutions have been obtained by using three system of beam resting on elastic foundation (BOEF) which was adopted previously by three different engineering software.
Abstract: In this study a numerical examples and solutions has been obtained by using three system of beam resting on elastic foundation (BOEF) which was adopted previously by three different engineering software. The first part of this paper was related to verify the model of (BOEF) by using ETABS2015 by make a comparison with previous results by determination the maximum settlements at the mid of span which show a good agreement between ETABS2015 and other results, where the total differences was vary from 2.13 % to 3.27%. . The second part of this study was highlighted on the settlement of BOEF with different parametric study (beam thickness, soil subgrade reaction(KS) and the load location), case (1) was selected for this goal. In this paper it is found that the differential settlement along the beam are decrease as increasing in the beam stiffness in addition to possibility to obtain uplift (positive settlement ) for some type of changing in the load location specially for higher thick beam . It was noticed that the settlement are increased significantly as reducing in the (KS). Finally this study show a different form of deflection by combination two of parametric study.

TL;DR: The North Carolina State Ports Authority (NCSPA) has undertaken improvements to its Morehead Port berth facilities, to better serve the deeper draft vessels utilized in today's shipping industry as discussed by the authors.
Abstract: The North Carolina State Ports Authority (NCSPA) has undertaken improvements to its Morehead Port berth facilities, to better serve the deeper draft vessels utilized in today's shipping industry. In general, the improvements include a layer of tieback to aid in carrying additional live loads from a recently constructed warehouse, and a combination of additional layers of tiebacks and a king pile wall system to stabilize the existing wall during the future removal of an existing rock berm and dredging along approximately 213.4 meters (700 feet) of the mudline to a deeper elevation. The Ports Authority commissioned an engineering study to determine a feasible approach to accomplish the improvements. The engineering study included a subsurface exploration to assess the subsurface profile, engineering properties of the in-situ soils, and configuration of an existing relieving platform behind the current wall system. The subsurface profile model was utilized in a detailed soil-structure interaction (SSI) analysis to design the new wall system. The design of the new wall system implemented innovative methodologies and construction sequencing to minimize the effects of the new wall on the existing wall system and warehouse. This paper highlights key features of the project. It describes the background information; project description; the design methodologies; soil exploration and determination of engineering parameters used in the SSI analysis of the new wall system; and incorporation of practical construction issues in the design.

TL;DR: In this article, the authors evaluate the behavior of soils on carrying capacity and permissible decreases of 100 mm using the finite element method by the help of Plaxis and the analogy approach is done by modeling the structure, foundation and soil coating load based on foundation conditions and CPT data.
Abstract: The stability of a structure is not only determined by the upper structure which directly bears the burden on the structure, but the stability of the lower structure in this case the foundation and capability of the subgrade support all loads to be very important. Good and accurate soil investigations are needed to calculate soil stability. Adequate soil investigations will not cause the estimated carrying capacity to be too low or high of foundation capacity. Design becomes uneconomical and recommendations given cannot be accepted in the worst conditions and even failures. Recently, one PLTG in Gorontalo was built with one operational support facility in the form of an oil tank. Investigation of soil in the oil tank area shows that the dense layer is at a depth of 2.5 meters below the ground level, and a solid layer is at a depth of 16 meters. This study aims to evaluate the behavior of soils on carrying capacity and permissible decreases of 100 mm. The analysis uses the finite-element method by the help of Plaxis. The analogy approach is done by modeling the structure, foundation and soil coating load based on foundation conditions and CPT data. The results of the analysis show that the carrying capacity of rolling and sliding is quite safe. Decrease in foundation subgrade meets the specified criteria so that the foundation soil is stable enough to support static and dynamic loads.
