RISA Unified Approach to H∠Control of Singular Markovian Jump Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper considers the H∠control problem for a class of singular Markovian jump systems (SMJSs), where the jumping signal is not always available. The main contribution of this paper introduces a new approach to a ...
Investigation on Crack of Long-span Prestressed Concrete Box Girder Bridges in Service
Publisher: American Society of Civil Engineers
Abstract: A research was performed for crack pathology of prestressed concrete box girder bridge (PCBGB). Cracking information of PCBGB in national scope was collected and investigated. Main crack types, distributing pattern and ...
Review of Study of Long-term Deflection for Long Span Prestressed Concrete Box-girder Bridge
Publisher: American Society of Civil Engineers
Abstract: The long-term deflection of Long Span Prestressed Concrete Box-girder Bridge (LSPCBB) is getting more and more serious in terms of structure safety. And there are still many ambiguous reasons as to the cause of the deflection ...
Exploratory Experimental Study on Fatigue Prestress Loss of Prestressed Concrete Beams
Publisher: American Society of Civil Engineers
Abstract: To study the fatigue prestress loss of prestressed concrete beams, four bonded post-tensioned bonded concrete simple supported beams were designed and constructed for constant-amplitude fatigue load displacement tests. ...
Long-Term Deflection Prediction and Correction of Creep and Shrinkage Model of High-Strength Concrete Based on Short-Term Measured Data for Bridge
Publisher: American Society of Civil Engineers
Abstract: To investigate the laws of creep and shrinkage in high-strength, concrete for long-span prestressed continuous box-girder bridge and predict long-term deflection, strain sensors were embedded in the midspan of a box-girder ...
