چکیده
Abstract Keramasan Bridge 2 is a bridge with an age of more than 30 years, so it necessary to review its feasibility and serviceability. Based on visual observations, there are signs cracks in the transverse longitudinal directions floor. results loading test, stated that deflection girder has exceeded allowable deflection, cause floor crack caused by non-uniform vertical movement girder. this, strengthen superstructure first before repairing The strengthening carried out installing diaphragm between girders. angled steel profile 100 mm x thickness 10 mm. To determine number position diaphragms, two alternatives were analyzed. alternative add three diaphragms at every 6.275 m distance second 3 distance. analysis show occurs girders after installation uniform. can increase uniformity structure up 8.12 times 6.60 respectively. Whereas stiffness 10.96 11.26 times, This shows adding provide rigidity compactness

Analysis of Girder Differential Deflection and Web Gap Stress for Rapid Assessment of Distortional Fatigue in Multi-Girder Steel Bridges
Distortion-induced fatigue cracking in unstiffened web gaps is common in steel bridges. Previous research by the Minnesota Department of Transportation (Mn/DOT) developed methods to predict the peak web gap stress and maximum differential deflection based upon field data and finite element analyses from two skew supported steel bridges with staggered bent-plate and cross-brace diaphragms, respe...
متن کاملNon-Chronological Approach in Crane Girder and Composite Steel Beam Installation: Case Study
The time delay and the structural stability are major issues in big size projects due to several factors. Improper planning and poor coordination lead to delay in construction, which sometimes result in reworking or rebuilding. This definitely increases the cost and time of project. This situation stresses the structural engineers to plan out of the limits of contemporary technology utilizing n...

متن کاملPrediction of Diaphragm Wall Deflection in Deep Excavations Using Evolutionary Support Vector Machine Inference Model (ESIM)
Problems in deep excavations are full of uncertain, vague, and incomplete information. In most instances, successfully solving such problems depends on experts' knowledge and experience. The primary object of this research was to propose an “Evolutionary Support Vector Machine Inference Model (ESIM)” to predict wall deformation in deep excavation in Taipei Basin. ESIM is developed based on a hy...
