Abstract:

Solid reinforced concrete slab foundations are commonly employed in the construction of multi-story frame and panel buildings on natural grounds, as well as in industrial structures such assilos, elevators, chimneys, steel reactors, and more.One significant advantage of monolithic foundations is their ability to be used on weak and uneven ground bases. These foundations can distribute uneven loads over a considerable area, redistributingthem to equalize the inevitable differential settlements of individual foundations. On soft and uneven soils, slab foundations are not only used to mitigate de

Abstract:

Layered periodic foundations (LPFs) with identical unit cells have been proposed as a type of seismic metamaterials due to the unique dynamic characteristic of attenuation zones. However, it is difficult to design attenuation zones with both comparatively low starting frequencies and large bandwidths for traditional LPFs with identical unit cells. In this paper, combined layered periodic foundations (CLPFs) are proposed by combining two traditional LPFs with different unit cells in tandem. Combined attenuation zones of the CLPFs are identified by investigating the frequency response functions

Offshore wind turbine foundations are commonly subjected to large horizontal, vertical, and bending moment loads.

Abstract:

Compared to reinforced concrete, steel structures are lighter and it is about 18 times more ductile than concrete. So, for high rise buildings steel structure can be a good choice. Theoretically, a lighter building will be less vulnerable to lateral forces. As a riverine country, pile foundations are commonly used as high-rise building foundations in Bangladesh. Pile foundations are frequently required to support lateral loads and moments, particularly in seismically active areas such as Bangladesh. This paper is based on the analysis of pile foundation due to lateral loading. The analysis was

Conventional ultimate limit state (ULS) shallow foundation design is typically based on a simplified analysis that fails to consider the possible existence of a combined structural and geotechnical failure, which is shown here to significantly affect the limit load. Neglecting this occurrence may lead to unsafe design, whereas a full analysis can be beneficial for the dimensioning. With the emphasis on separate serviceability limit state and ULS design in modern design codes such as Eurocode 7 (EN 1997-1, 2004 edition), this paper explores unsafe loading scenarios and the benefits to be gained

Abstract:

The pile foundation is the lower building structure that supports the above structure. Pile foundations withstand combined loads from the vertical and horizontal directions. In the field, both loads work simultaneously. However, in Indonesia, in general, the axial and lateral loading tests are carried out separately. Related to this, there have been few investigations on the influence of combined loads on pile foundations. These led to inconsistent results to the effects of adding the axial load on the lateral loading. The three-dimensional finite element method is used in this study to analyz

Abstract:

In the last few decades, it has been observed that raft foundations are very commonly used as a foundation solution for moderate to high rise structures either by resting on stone columns or on piles in soft soils. It is believed that, combining stone columns and piles in one foundation system is the more suitable foundation for medium rise structures. The combined foundation system provides a superior and more economical alternative to pile, and a more attractive alternative to stone columns in respect to ground improvement.

It is well known that a raft foundation is, in most cases, a more economical alternative to a conventional pile foundation. The concept of incorporating a raft into a piled system is not new and has been implemented in foundation design in several Western countries. However, the practical implementation of this concept remains limited and largely absent. Ukrainian design codes only mention the existence of combined pile-raft foundations (CPRFs) and the possibility of their application. In CPRFs, both components—the raft and the piles—act as load-bearing elements, and their design must follow o

Abstract:

Based on the axisymmetric model, the consolidation control equations based on the assumption of equal strain are established for the vertical drains-impervious columns multi-composite foundation consolidation problem, and the analytical solutions are given for the drains-impervious columns multiple composite foundation consolidation with trapezoidal, rectangular, positive triangular and inverted triangular distribution of initial pore pressure. Through the degradation study and comparison with the existing analytical solutions. Using the derived consolidation analytical solution for parameter

Abstract:

The use of supplemental damping to dissipate seismic energy is one of the most economical and effective ways to mitigate the effects of earthquakes on structures. Both displacement-dependent and velocity-dependent devices dissipate earthquake-induced energy effectively. Combining displacement-dependent and velocity-dependent devices for seismic mitigation of structures minimizes the shortcomings of individual dampers, and is the most economical solution. Previous studies have focused on reducing seismic responses of a damped structure without considering the consequence of the unbounded founda

Abstract:

In extreme marine environments, the interaction between offshore wind turbine pile foundations (OWTPFs) is critical, and the associated hydrodynamic loads are complex. This study focused on fixed OWTPFs and used computational fluid dynamics (CFD) to numerically simulate the flow field around pile foundations under the combined action of focusing waves and current. The objective was to investigate the influence of different focusing wave and current parameters on the hydrodynamic properties of the pile foundations. The findings indicate the following: (1) When the wave and current directions ar

Abstract:

In the last two decades, there has been a significant increase in infrastructure development on slopes of hilly regions of the world, due to population growth. There are many infrastructures on unsaturated expansive slopes, especially in semi-arid and arid regions. Rainfall infiltration is one of the major factors that contributes to the slope and infrastructure foundations failures on hilly slopes with unsaturated expansive soils. In the current study, a rational approach is proposed considering the combined influence of the foundation-slope behavior based on the principles of unsaturated soi

Abstract:

The paper presents the main stages of designing the strengthening of shallow foundations with piles made in clay soil (injection and bored-injection) for reconstructed buildings. Such foundations are often called combined foundations. The basic methods for installing these piles as part of reinforced foundations are presented, including injection cylindrical piles, bored-injection cylindrical piles of Titan and Atlant types, and bored-injection conical piles. The methodology of foundation strengthening design with the use of such piles is discussed. As a result of investigations of soil proper

Formulation of the problem. In the field of construction of multi-story and high-rise buildings, with significant loads on the foundation, especially in the presence of weak water-saturated soils on top, pile-slab foundations are usually used to meet the requirements of the normative document [4] for maximum permissible deformations. The possibility of using slab foundations in this case must be confirmed by calculations with a scientific and technical justification of the accepted model of the soil foundation and its parameters. The purpose of the is to substantiate the application of the mod

Abstract:

Existing buildings which do not satisfy modern seismic design requirements may be rehabilitated economically by the addition of steel bracing or reinforced concrete shear walls. However, steel bracing and concrete shear walls can place severe demands on the building foundation, and the existing foundations are likely to be inadequate. Strengthening of existing foundations may be exceedingly expensive, and the cost of the foundation work may dominate the seismic retrofit effort. Several foundation retrofit strategies are described and discussed. These strategies are invariably expensive, and th
