Abstract:

Due to geological conditions at abutment, working mechanism and economy, a prestressed concrete bridge with double cantilevers is designed. Main dimensions and drawings are introduced and static analytical results of prestressed concrete cantilever bridge are discussed. The numerical model was built by the integrated solution system for bridge and civil Engineering-MIDAS/Civil. The main loads which affect internal force and deflection at key sections of bridge are studied, such as mid-point, support point and free end of cantilever bridge. The rules which loads affect internal forces and defle

The name Balance Cantilever Bridge is arrived due to the application of construction methodology which balances out the cantilever portion. It is one of the most effective methods of building bridges without the need of false work. Balanced cantilever bridges are used for special requirements like construction over traffic, short lead time compared to steel and use local labour and materials.

The simple-supported beam bridge is a common structure form widely used in small and medium span bridges. When the span is longer, the maximum bending moment is accordingly bigger. The maximum positive and negative bending moment numerical of beam decreases obviously because of cantilever bridge with cantilever beams to reduce the amount of materials. This article analyzes the current commonly used cantilever bridge with large span.

This study aims to develop and evaluate vibration-based piezoelectric energy harvesters for generating power from a bridge structure. New designs of multiple-degree-of-freedom (DOF) cantilevers were proposed and evaluated in a laboratory and on a full-scale bridge.

Structural deformation control of constructed bridges not only affects the alignment of the bridge, it is also the key to ensure safety.

Abstract Deterioration of bridge conditions can be caused by material durability, traffic volume and load, environmental conditions, or natural disasters. For this reason, bridge rehabilitation activities are needed. The bridge rehabili-tation process often results in road access being cut off and the handling process takes quite a long time. To prevent isolated areas to happen, it is necessary to build emergency bridges, which are usually called steel frame panel bridges or also known as Bailey Bridges.

Abstract:

A characteristic feature of many long-span cantilever prestressed concrete bridges are excessive deflections of their spans due to the rheological processes in the concrete and in the prestressing steel. Such bridges are subject to monitoring during which geodetic surveys are usually conducted. The latter reveal changes in the deflection curves of the spans. In this paper span displacements resulting from concrete creep are analysed. A specific situation occurring when the span static scheme is changed from the cantilever (assembly stage) to continuous beam (exploitation stage) is considered.

Abstract The cantilever concreting technology is one of modern methods of constructing the concrete long-span bridges. The fundamental features of this method are saving of materials and of construction costs (especially of scaffolding and of formwork) and first of all a possibility of carrying out the construction of the span in many spots at the same time. The negative feature of these bridges is a large long-term deflection of the bridge, as a result of rheological processes in the concrete and in the pre-tensioning steel.

Cantilever fixed partial dentures are defined as having one or more abutments at one end of the prosthesis while the other end is unsupported. Much controversy without documentary evidence has surrounded this prosthesis. Despite negative arguments, the cantilever prosthesis has been used extensively by the clinicians. If used nonjudiciously without following proper guidelines these might lead to some complications. Although complications may be an indication that clinical failure has occurred, this is not typically the case. It is also possible that complications may reflect substandard care.

In the Bridge project, design and analysis include two main components: preliminary design and detailed design, to integrate Building Information Modeling (BIM) in the design process of the Bridge. Firstly 3D modelling of the Bridge needs to be carried out, that means. It has transferred 2D drawing into 3D models. The BIM mainly focuses on modelling analysis, detection and feedback and design. Cantilever bridge construction is a step-by-step construction of a cantilever in segments and stitching them to segments previously casted by prestressing. When the cantilever segments are added to both

Abstract:

The main bridge of Yunshi Hanjiang River Bridge is a prestressed concrete extradosed bridge with two pylons, a single cable plane and with span arrangement (128+238+128) m. The main girder of the bridge is the concrete continuous triple-cell single box girder of long cantilevers and variable sections, the box girder is 26.5m wide. The cantilever of girder is 5.75m wide as to reduce the self-weight of main girder. In the design, the software Dr.Bridge was used to establish the finite element model for the box girder and to carry out the global calculation of the girder lateral calculation. The

Abstract:

Joints between segments in cantilever casting concrete bridges require special attention in design and construction. These joints introduce discontinuity in the bridge; furthermore weaken the connection stiffness and strength of corresponding section, which may lead to excessive downwarping of bridge. Experiments were conducted to assess the shear stiffness of segmental joints section. The parameters studied included monolithic non-joints, joints roughened, joints roughened with shear-key. It was found that the shear stiffness of jointed section is largely lower than that of non-jointed sectio

To evaluate the vulnerability of bridges at various construction stages under the action of strong earthquakes, the incremental dynamic analysis (IDA) method is applied, and the vulnerabilities of a continuous girder case study bridge with the cast-in-place cantilever construction method, which owns five main construction stages, are evaluated and compared. The results show the following: With the increase in the peak ground acceleration (PGA), the vulnerabilities of bridges at different construction stages all increase.

Abstract:

Cable-stayed bridges are ideal for spanning natural barriers of wide rivers, deep valleys, or ravines, and for pedestrian bridges crossing wide interstate highways. Modern construction of cable-stayed bridges makes use of the segmental balanced cantilever techniques and involves many repetitive cycles of placing the concrete segments (both cast-in-place and precast) and supporting cables. It provides a fertile area for the application of computer simulation techniques for the planning and analysis of the process, particularly for studying the interaction of resources used in the construction p

There will be such problems of cantilever beam segment closed error and the bridge line-type do not coincide in design goals.

Abstract:

Multifrequency atomic force microscopy (AFM) utilizes the multimode operation of cantilevers to achieve rapid high-resolution imaging and extract multiple properties. However, the higher-order modal response of traditional rectangular cantilever is weaker in air, which affects the sensitivity of multifrequency AFM detection. To address this issue, we previously proposed a bridge/cantilever coupled system model to enhance the higher-order modal response of the cantilever. This model is simpler and less costly than other enhancement methods, making it easier to be widely used. However, previous

Abstract:

Construction of bridges is associated with uncertainties that rise due to unavailability of resources, equipment breakdown and/or working environment. Bridge construction techniques can be grouped into six main categories: 1) cast‐in‐situ on false work, 2) cantilever carriage, 3) stepping formwork, 4) launching girder, 5) pre‐cast balanced cantilever, and 6) incremental launching. The latter technique is characterised by minimising the use of falsework. Further, the fabrication and casting of bridge segments are executed at a stationary location, named casting yard (which includes several faci
