In the present work, behavior of inoxydable steel as reinforcement bar in composite concrete is being investigated. The bar-concrete adherence in reinforced concrete (RC) beam is studied and focus is made on the tension stiffening parameter. This study highlighted an approach to observe this interaction behavior in bending test instead of direct tension as per reported in many references. The a...

Reinforced concrete structures consists of two main components and the behavior of these structures influenced by gender and material properties, in order to investigate the behavior of concrete reinforced beam that most important flexural element in reinforced concrete structures, we chosen High Strength Concrete (HSC) for concrete and GFRP and steel bars for reinforcement. For compare the new...

This paper is focused on the suitability of selection parameters supporting structure bridge crane for needs cross-section optimization. The cross section beam analysed in terms its rigidity and dimensions with respect to span crane. When optimizing reduce overall weight, recommendations are given address issue cross-sectional stability. An iterative procedure design at specified load capacity ...

Metode pelaksanaan erection steel box girder pada proyek relokasi jembatan antelope km 5+145Bekasi-Jawa Barat merupakan duplikasi Jembatan Antelope yang salah satu jembatancrossing di atas Ruas Jalan Tol Jakarta-Cikampek. eksisting bersinggungan dengan rencana jalurkeret cepat Bekasi-Jawa (KCJB) sehingga perlu direlokasi. Panjang main span termasuk kedua jalanlayang pendekat adalah 300 m, semen...

Purpose: There are many bridges being constructed in Nepal. Brides of different types like Bailey truss, cable stayed, RCC Arch, pre-stressed, Slab, T-Beam, Steel Box, Stone masonry arch, suspension, and suspended tendered at present Most the T-beam Prestressed bridges. It has been found need to carry out research develop logical price adjustment coefficient ranges for contracts make provision ...

Based on Zhonghua Road Bridge in Liaocheng city, a single tower hybrid cable-stayed bridge, the stress of steelconcrete joint girder is studied using finite element method with software MIDAS and ANSYS. The beam model whole bridge established CIVIL, from which internal forces critical sections steel–concrete under six adverse conditions are obtained. Then, results applied refined solid-shell Wi...

background: the presence of a wedge filter in the beam trajectory can modify the beam quality and cause some changes in the dosimetry parameters which are usually difficult to be measured directly and accurately. material and methods: in this study the mcnp-4c monte carlo code was used to simulate the 9 mv photon beam generated by a linear accelerator. upon getting a good agreement between the ...

In this paper the parametric study is carried out to investigate the effect of number of cells in optimal cost of the non-prismatic reinforced concrete (RC) box girder bridges. The variables are geometry of cross section, tapered length, concrete strength and reinforcement of the box girders and slabs that are obtained using ECBO metaheuristic algorithm. The design is based on AASHTO standard s...

this paper presents the results of analytical studies concerning the flexuralstrengthening of reinforced concrete beams by external bonding of high-strength lightweightcarbon fiber reinforced plastic (cfrp) plates to tension face of the beam. three groups of beamswere tested analytically and compared with existing experimental results. results of the numericalanalyses showed that, although addi...
