RISSimplified Simulation Method for Hysteretic Behavior of Wood Brackets
Publisher: ASCE
Abstract: Because of its high historical, cultural, and scientific value, wooden architectural heritage in East Asia requires comprehensive protection. The dou-gong (bracket set) is an essential member in ancient Chinese wooden ...
Theoretical Design and Dynamic Analysis of a Quasi-Zero Stiffness Device Using Precompressed Springs as Negative Stiffness Component
Publisher: ASCE
Abstract: Based on the principle of parallel connection of positive and negative stiffness structures, a new quasizero stiffness (QZS) isolation device is proposed in which the negative stiffness structure is designed by a nonlinear ...
Pavement Rehabilitation Strategy Selection for Steel Suspension Bridges Based on Probabilistic Life-Cycle Cost Analysis
Publisher: American Society of Civil Engineers
Abstract: Field inspections on long-span steel suspension bridges in China reveal that the pavements undergo a fast deterioration process attributed to the flexibility of suspension bridges and the heavy traffic loads. Such extensive ...
Comparison of Ambient Vibration Response of the Runyang Suspension Bridge under Skew Winds with Time-Domain Numerical Predictions
Publisher: American Society of Civil Engineers
Abstract: Existing buffeting theories and methods for dealing with skew winds are summarized. A modified version of the mean wind decomposition method is described that directly uses wind monitoring data from structural health ...
Sensitivity and Reliability Analysis of a Self-Anchored Suspension Bridge
Publisher: American Society of Civil Engineers
Abstract: This paper presents a sensitivity and reliability analysis of a self-anchored suspension bridge by applying a new hybrid method proposed by the authors based on integration of the Latin hypercube sampling technique (LHS), ...
Pounding Analysis of Isolated Girder Bridge under Nonpulse and Pulse-Like Earthquakes
Publisher: ASCE
Abstract: Pounding damages are frequently encountered in concrete continuous girder bridges during strong earthquakes. In the evaluation of pounding responses, the simplified lumped mass model with the contact element are usually ...
Experimental Study on Corrosion-Fretting Fatigue Behavior of Bridge Cable Wires
Publisher: ASCE
Abstract: Bridge cables are often subjected to tensile stress variation, interior contact stress, and corrosion environment, resulting in premature failure of wires. This paper experimentally investigates the behavior of bridge wires ...
Structural Parameter Identification of Ancient Stone Arch Bridge via Three-Dimensional Laser Ranger Scanning
Publisher: ASCE
Abstract: Stone arch bridges are symbols of a shared civil engineering heritage worldwide, but they suffer from damage caused by various natural disasters that have occurred during their long service. The basis of ancient bridge ...
Nondestructive Tree Planting for Reducing the Wind Loads of a Historical Wooden Pagoda
Publisher: American Society of Civil Engineers
Abstract: Historical wooden pagodas are found in several Asian countries and are considered priceless world heritage values due to their majestic appearance and exquisite manufacturing techniques. Over time, the structure may occur ...
Simulation and Measurement of Human-Induced Vibrations of the Beijing Olympic Watchtower with Tuned Mass Dampers
Publisher: American Society of Civil Engineers
Abstract: The Beijing Olympic Watchtower (BOW) is a landmark building with irregular shape and complex structural configuration; however, excessive human-induced vibrations of the sightseeing platform may occur during service, ...
