Lateral Loads and Displacements of Railroad Bridges from Field Investigations
Publisher: ASCE
Abstract: The progressive increase in loads and frequency of trains traversing over aging railway infrastructure can lead to large lateral forces and displacements that could potentially cause derailment and problems related to ...
Hybrid Model for Railroad Bridge Dynamics
Publisher: American Society of Civil Engineers
Measuring Total Transverse Reference-Free Displacements of Railroad Bridges Using Two Degrees of Freedom: Experimental Validation
Publisher: American Society of Civil Engineers
Abstract: Knowing the extent of displacement experienced by railroad bridges when loaded is useful when evaluating the safety and serviceability of the bridge. However, measuring displacements under train crossing events is difficult. ...
Noncontact Dynamic Displacement Measurement of Structures Using a Moving Laser Doppler Vibrometer
Publisher: American Society of Civil Engineers
Abstract: Monitoring of bridge displacements is critical for safe and cost-effective railroad operations. One of the essential parameters for determining the serviceability of the bridges is the dynamic displacement of the bridge ...
