چکیده
In this study, the optimisation design problem of steel-concrete composite sections in simple girder bridges is developed. Design variables including thickness desk and dimensions section are discrete to reflect realistic works. The total cost steel objective function that minimised. requirements geometry, load-carrying capacity, deformation provided TCVN 11823:2017 standard used as constraints. above solved by using Harmony Search (HS) algorithm. A 42(m) studied. numerical results show optimal designs save about 15% compared conventional method. It can be concluded applying beams brings high efficiency it easily applied practice.

Economical Steel Plate Girder Bridges
As a service to the bridge design profession, Bethlehem Steel has conducted hundreds of studies of steel plate girder bridges using its Preliminary Bridge Girder Optimization Program. The program is unique because it optimizes plate girder designs on the basis of least cost, not least weight. An evaluation of many study results leads to a number of guidelines which are offered in this paper. Wh...
متن کاملExperimental and Numerical Investigation on Bending Capacity of Steel- concrete Composite Truss Girder
This article presents an experimental investigation on the bending capacity of steel-concrete composite truss girder (SCCTG). Four full-scale specimens named CB1, CB2a, CB2b and CB3 respectively, are tested and numerical analyzed. Stress distribution, load-displacement relationship, load-slip relationship and ultimate bending capacity of SCCTGs are investigated. The results show that SCCTG foll...
متن کاملComposite Action during Construction of Steel Trapezoidal Box Girder Bridges (0-1898-2)
In steel trapezoidal box girder bridge systems, the U-shaped steel girder is designed to act compositely with the concrete deck to form a closed box for live loading. During the construction stage, however, the behavior is not well understood. The usual practice of assuming the system to be non-composite during construction requires substantial top flange bracing to form a quasi-closed box sect...
متن کاملPrestressed Concrete Girder Bridges Using Large 0.7 Inch Strands
The National Bridge Inventory (NBI) includes more than 600,000 bridges within the United States of Prestressed concrete girder bridges represent one of the most widely used bridge systems. The majority of these girder bridges were constructed using 0.5 and 0.6 inch diameter strands. The main impediments to using larger strand diameters are: 1) bed capacities, 2) lack of structural knowledge reg...
