Abstract: The seepage control system of a high Concrete Face Rock-Fill Dam (CFRD) may have anti-seepage deficiencies during both construction and operation. In order to solve these, the three-dimensional Finite Element Method (FEM) model was built based on dam body filling, anti-seepage system, defect location and bedrock distribution. The seepage field simulation and computation were carried o...

In recent years, the corrosion of steel reinforcement has become a major problem in the construction industry. Therefore, much attention has been given to developing methods of predicting the service life of reinforced concrete structures. The progress of corrosion cannot be visually assessed until a crack or a delamination appears. The corrosion process can be tracked using several electrochem...

The scope of this study is to look at the effect supplying a non-prismatic cross-section on flexural strength one-way continuous slabs reinforced concrete (RC) with two spans under repeated load. research aims ability increase stiffness which leads saving construction costs. For purpose, experimental investigations were carried out; work consisted fabrication and testing six two-span RC same vo...

ABSTRACT The maturity method is a procedure that associates the evolution of temperature concrete cast to structure and its hardened state properties like compressive strength, usually at early ages. Its use justified when safety agility are required for activities prestressing, shoring removal, demolding low curing analysis. Temperate regions known having lower temperatures during winter, whic...

Standard fire resistance tests and post-fire on residual mechanical properties were carried out two four-edge simply supported reinforced truss concrete two-way composite slabs with wide seam splicing (“integral seam”) close (“separated seam”), the effects of different forms during after exposure to high temperatures explored. The results indicate that there are significant differences in terms...

A semi-slab of precast concrete (or half-slab) is a structural system that consists at the bottom half slab and cast in situ top. To avoid traditional formwork minimize slab, this section can function as reduce thickness slabs, which makes their transportation easy. The interface between overtopping effective for system's performance. improve half-slab floor system, it needed to have shear conn...

This paper presents a comparison of the properties of concrete slabs when two types of fibres are added. One specimen had no fibres and acted as a control specimen. The remaining four specimens had steel and polypropylene fibres added in the volumetric ratio of 0.5% and 1.0%. The dimensions of the slab specimens were 820×820×80 mm and were supported by four rollers at their edges. A displacemen...

In this paper, a reinforced concrete(RC) bridge built in an interchange, in the city of Kerman (a city located in south of Iran) is examined by the Structural Health Monitoring (SHM) system. During the construction of this bridge such as; the main beams, slab, and retaining walls, some Electrical Strain Gauges were mounted on the main reinforcements at different locations within the body of thi...
