RISAdaptive Network–Fuzzy Inferencing to Estimate Concrete Strength Using Mix Design
Publisher: American Society of Civil Engineers
Abstract: Proportioning of concrete mixes is carried out in accordance with specified code information, specifications, and past experiences. Typically, concrete mix companies use different mix designs that are used to establish ...
Risk-Based Seismic Retrofit Prioritization of Reinforced Concrete Civic Infrastructure: Case Study for State of Oregon Schools and Emergency Facilities
Publisher: American Society of Civil Engineers
Abstract: The state of Oregon is in a high seismic hazard zone, which raises serious concerns for potential damage, even collapse, of older concrete schools buildings and emergency facilities. In order to allocate retrofit prioritization ...
Bayesian Belief Network to Assess Carbonation-Induced Corrosion in Reinforced Concrete
Publisher: American Society of Civil Engineers
Abstract: Corrosion of reinforcing steel is a major cause of deterioration of reinforced concrete structures. Two primary causes leading to corrosion of reinforcing steel are, respectively, carbonation and chloride contamination of ...
Comparison of Statistical Models for Predicting Pipe Failures: Illustrative Example with the City of Calgary Water Main Failure
Publisher: American Society of Civil Engineers
Abstract: Several statistical models have been proposed to study effects of different covariates in the failure of water pipes. In this paper, three statistical models, the Weibull proportional hazard model (WPHM), the Cox proportional ...
CLT–Steel Hybrid System: Ductility and Overstrength Values Based on Static Pushover Analysis
Publisher: American Society of Civil Engineers
Abstract: A timber-steel hybrid system, where cross-laminated timber (CLT) shear panels are used as infill in steel moment resisting frames, is analytically investigated. The proposed hybrid system combines ductile behavior of steel ...
Comparison of Seismic Performance of a RC Frame Building before and after the Wenchuan Earthquake in Sichuan Province
Publisher: American Society of Civil Engineers
Abstract: The Wenchuan earthquake that occurred in China in 2008 caused extensive damage and loss of life and property. Comparison of the vulnerabilities between former and current reinforced concrete (RC) frame structures after the ...
Equivalent Viscous Damping for Steel Moment-Resisting Frames with Cross-Laminated Timber Infill Walls
Publisher: American Society of Civil Engineers
Abstract: In the direct displacement-based design method, energy dissipative capacity of structures can be represented by an equivalent viscous damping (EVD). A number of studies have been reported in the formulation of EVD for ...

Publisher: American Society of Civil Engineers
Abstract: In the direct displacement-based design method, energy dissipative capacity of structures can be represented by an equivalent viscous damping (EVD). A number of studies have been reported in the formulation of EVD for ...
Damage Assessment of Connections Used in Cross-Laminated Timber Subject to Cyclic Loads
Publisher: American Society of Civil Engineers
Abstract: Cross-laminated timber (CLT) products are gaining popularity in the North American market and are being used in midrise wood buildings, in particular, in shearwall applications. Shearwalls provide resistance to lateral ...
Seismic Base Shear Modification Factors for Timber-Steel Hybrid Structure: Collapse Risk Assessment Approach
Publisher: American Society of Civil Engineers
Abstract: In this paper, to supplement the Canadian building code for a timber-steel hybrid structure, over-strength, and ductility-related force modification factors are developed and validated using a collapse risk assessment ...
