OVERVIEW The efficacy of modal analysis in detecting and localizing damage is debated based on sensitivity concerns – modal frequencies are extremely insensitive to small changes in local parameters and geometry. Convincing evidence of sensitivity issues is vast, and here we cite a single field study of a 163 ft. long, 10 ft. deep experimental test girder from an I40 bridge in Bernalilo County ...

This study investigates the seismic behavior of deconstructable composite steel/concrete floor systems consisting of precast concrete planks and deconstructable clamping connections attaching the planks to the steel floor beams. The system is proposed to promote sustainable design of composite steel/concrete floor systems in steel buildings via reuse of the structural steel and concrete compone...

In order to study the flutter of long-span pedestrian suspension bridge and its aerodynamic control, a 420m-span is used as an engineering example, wind-induced vibration seven particular sections studied by wind tunnel tests, soft phenomenon two kinds identified. The results show that fairing wind-retaining plate measures are not necessarily effective improve stability bridge, these may reduce...

Several theories are available in the literature to predict ultimate shear resistance of plate girders, generally known as tension field theories. It is already found out, by many researchers, that prediction majority models mostly over-conservative for non-rigid end post steel girders. So, there a need development accurate finite element models, which could strength better than theoretical mod...

This paper presents a practical procedure for creating finite element (FE) model vibration analysis of cruise ships. The most preferable FE modelling approaches are studied and discussed through case studies common ship structures, which cover the range from low to high frequencies. application homogenized equivalent single layer (ESL) theory based stiffened panel is extended local forced analy...

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...

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...
