There are multiple configurations permitted for a cable stayed bridge such as the number of spans, tower shapes, and cable arrangements. Therefore it is always important to study the behaviour of these types of structures against strong winds so that aeroelastic instabilities do not appear. This paper contains detailed aeroelastic analyses of three cable stayed bridges of very different configu...

© 2012 IBRACON The studied connections are composed of concrete filled steel tubes (CFT) connected to composite beams by passing through bolts, endplates and steel deck, which also contributes to support the applied loads. The parametric analysis presented in this work is based on numerical simulations performed with software TNO Diana, using experimental results to calibrate the reference nume...

Abstract UHPFRC is a new concrete technology being used in many countries including Malaysia. favourable material properties open up potential for precast options bridge construction and have been widely as beams highway bridges Nevertheless, PRC were preferred despite heavy weight large sections although these affect the design of substructure well cost construction. This research to review ap...

Introduction: The determination of accurate dose distribution is an issue of fundamental importance in radiotherapy, especially with regard to the fact that the human body is a heterogeneous medium. Therefore, the present study aimed to analyze the density and isodose depth profiles of 6 MV beam in a SP34 slab-wooden dust (pine)-SP34 slab (SWS) heterogeneous phantom.  Materials and Methods: Th...

The good cladding of a large-sized Nd-doped phosphate glass slab as laser amplifier requires not only the amplified spontaneous emission and parasitic oscillation to be fully absorbed, hold up small signal gain coefficient Nd ions, but also absorbed heat energy appropriately dissipated extend uniform temperature field for larger beam aperture edge-cladded Nd–glass slab. In present work, numeric...

The short-headed stud connectors play a critical role on the interaction of orthotropic steel deck (OSD) and ultra-high performance concrete (UHPC) layer in steel-UHPC composite bridge deck. In this paper, fatigue behavior these was experimentally investigated beam test. failure modes were identified classified into 5 types. test results analyzed by linear regression analysis neglecting run-out...

Plane-wave pseudopotential Density Functional Theory (OFT) periodic slab calculations were performed usingthe giteralized gradient approximation (GHA) to investigate the adsorption of nitric oxide(NO) on the (I II)surface of Cu. Copper rface was stimulated using th P 'odic Slab Method consisting of Five atomic Layers.Four different adsorption saes (Atop. Bridge, RCP Hollow, and FCC Hollow) were...

Verification of the serviceability limit state of vibrations due to traffic live loads can be neglected in conventional types of concrete road bridges but becomes critical in the design of slender structures like Under-Deck CableStayed bridges. The novelty of the work presented in this article is that an innovative vehicle-bridge interaction model is employed, in which realistic wheel dimension...
