Abstract (sommario):

The thickness of the raft slab is determined by punching shear. The raft slab is commonly thick, which causes concrete volume is large. Mass concrete can bring disadvantage to the foundation. In order to increase the bearing capacity and reduce the thickness, it is suggested that the raft slab to be reinforced by steel fibers. There are five groups of specimens in this paper. S1 is the common reinforced concrete slab. S2 and S3 are concrete slabs reinforced by steel fibers broadcasted layer by layer when casting specimen.

Abstract (sommario):

Abstract Raft foundations are essentially a slab that extends the entire length of the building, sustaining and dispersing its mass to the earth. A pile foundation is a collection of columns that are erected or inserted into the ground to distribute weight to the subsoil underneath. A pile is a long, cylindrical construction made made of a sturdy substance such as concrete. Building loads are transferred to hard strata, rocks, or high-bearing-capacity soil using piles. Pinned raft foundations are a combination of a pile and a raft slab. They’re frequently used for large structures and when the

It’s a good mean to develop underground business street. But at South China, usually the underground water level is higher, while the weight of structures is smaller, so it causes a prominent problem—anti-floating of structures. These cases of failure including both whole anti-floating and partial anti-floating are reported occasionally. To thoroughly solve the problem of anti-floating, the foundation design of underground street structure is particularly important. At present there are two kinds of foundation design scheme of the underground street. The First is raft foundation plus anti-floa

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

This paper presents the authors’ research results from an analysis of intermediate foundations as well as slab and pile foundations in the context of soil consolidation. Looking at soil as a building material that changes its properties over time is very important from the point of view of the safety of construction, implementation, and operation of building structures. In addition, soil can be parameterized in such a way as to accurately describe its possible behavior under service loading. Of great interest is the phenomenon of consolidation, which is based on the reduction of soil volume ov

Abstract (sommario):

Despite considerable research concerning the manifestation of greenhouse gases in the usage of buildings, little has been done concerning emissions arising from the construction process itself. This paper specifically examines emissions arising from cut and fill excavation on residential construction sites. Even though such excavation is often seen as being economical in terms of providing a flat base for concrete raft slab construction, the environmental consequences of this approach need to be considered more fully in terms of impact on the environment. This is particularly important when st

Abstract (sommario):

Pile–raft foundations are widely used in soft soil engineering due to their good integrity and high stiffness. However, traditional design methods independently design pile–raft foundations and superstructures, ignoring their interaction. This leads to significant deviations from actual conditions when the superstructure height increases, resulting in excessive costs and adverse effects on building stability. This study experimentally investigates the interaction characteristics of pile–raft foundations and superstructures in soft soil under different working conditions using a 1:10 geometric

In the projects of buildings and structures, in the last two to twenty-five years, in world practice, the so-called combined pile raft foundation (CPRF) is increasingly used, for which, in the design and calculations, it is assumed that the calculated load from the building is distributed between the piles and the raft, allowing up to 50% inclusion in the work (resistance) of the raft. As part of the scientific and technical support [1-8] of the construction object, instrumental automated monitoring of the stress state of the «soil foundation - combined pile raft foundation» system of the mult

Glaciation in the area of Charlie Lake, New Brunswick, has produced a granitic till very similar in appearance to weathered bedrock. Portions of weathered granite were moved intact and redeposited as imbricated rafts under basal till. The rafts vary from 0.3 to 2 m in thickness over a 10 m wide exposure and show deep weathering zones and brittle deformation, despite the fact that they are highly friable. The rafts are separated by glacigenic fault planes defined by lenses of diamict and rare clasts of distant origin. They are recognizable only in excavations where fault planes can be seen to d

Abstract Lignite coal (LC) is a key energy source for electricity generation in Turkey. During lignite burning, huge amounts of fly ash (FA), bottom ash and slag are produced as by-products which contain radionuclides in the natural radioactive series of uranium and thorium, and radioactive potassium. These radionuclides may lead to radiological exposure of workers and the public and cause environmental problems. Therefore, finding diverse uses for the by-products in the construction sector and earthwork applications has considerable economic and environmental importance. In this study, the ac

Abstract: India's rapid urbanization and diverse geological conditions pose significant challenges to traditional foundation systems. Conventional foundations, such as raft and isolated footings, often struggle to support structures in flood-prone regions, seismic zones, and areas with weak soil conditions. The increasing frequency of natural disasters, soil erosion, and groundwater fluctuations further complicates the stability of buildings and infrastructure. To address these challenges, Hybrid Foundations—a combination of shallow and deep foundation techniques—are emerging as a viable solut

Abstract (sommario):

The scene flow estimation methods make significant progress by estimating pixel-wise 3D motion on implicitly learning a motion embedding using an end-to-end differentiable optimization framework. However, the motion embedding learned implicitly is insufficient for grouping pixels into rigid object in challenging regions, such as occlusion and inconsistent multi-view geometric properties. To address this issue, we propose a novel method for estimating scene flow called OAMaskFlow, which has three novelties. Firstly, we propose the concept of occlusion-aware motion (OAM) mask and generate the gr

Abstract (sommario):

When designing building frames for seismic reasons, the effect of soil flexibility is typically disregarded, and the design is executed using the outcomes of dynamic analysis with a fixed base condition. Because the overall lateral stiffness of the structure decreases as a result of soil flexibility, the lateral natural period lengthens. The building frames situated on the Raft foundation may experience a significant change in seismic response due to this extension of the lateral natural period (T). Therefore, it is imperative to consider the soil's flexibility, also known as soil structure in

Abstract The adaptor protein SAP regulates signaling through signaling lymphocytic activation molecule (SLAM)–family receptors expressed on T and natural killer (NK) cells. In patients affected by X-linked lymphoproliferative (XLP) disease, mutations in the SH2D1A gene result in defective lytic activity. However, the mechanism by which SAP controls cytotoxic activity remains unclear. T-cell–receptor (TCR) activation of CD8+ cytotoxic T cells (CTLs) results in down-regulation of SAP, suggesting that this protein is involved in early activation events. Here, we show that SAP-deficient CTLs from
