A Neural Network-Based Multivariate Seismic Classifier For Simultaneous Post-Earthquake Fragility Estimation And Damage Classification, Xinzhe Yuan, Genda Chen, Pu Jiao, Liujun Li, Jun Han, Haibin Zhang
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
A scalar intensity measure (IM) could be insufficient to represent the earthquake intensity and variety in fragility estimation. Introducing multiple IMs to conventional regression of fragility functions can be computationally demanding and require priori assumptions of functional forms. In this study, multivariate seismic classifiers with multiple IMs as inputs are developed based on artificial neural networks (ANNs) to address the above disadvantages of traditional regression approaches. Case studies of a four-story code-conforming benchmark building indicate that fragility estimates from multi-IM ANN classifiers lead to higher accuracy (5.0% to 7.7%) in system-level and element-level damage classification than the single-IM traditional fragility …

Simplified Analytical Model To Assess Key Factors Influenced By Fiber Alignment And Their Effect On Tensile Performance Of Uhpc, Le Teng, Huanghuang Huang, Kamal Khayat, Xiaojian Gao
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
The increase in single-fiber pullout strength usually improves tensile strength and toughness of UHPC. An increase in fiber orientation angle (θ) up to 45° to the direction of pullout load was found to enhance the single-fiber pullout strength. However, such increase in predominant θ value along tensile strength specimens led to a reduction in tensile strength of UHPC. In order to elucidate this controversial observation, analytical models combined with experiments were carried out to assess the key factors influencing the tensile properties of UHPC due to variations of fiber orientation. The test parameters involved the evaluation of the effect of …

Revealing Bluff-Body Aerodynamics On Low-Rise Buildings Under Tornadic Winds Using Numerical Laboratory Tornado Simulator, Ryan Honerkamp, Guirong Grace Yan, John Van De Lindt
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Tornadoes result in death and property loss in communities around the world. To quantify the actions of tornadoes on civil structures, researchers have built physical laboratory tornado simulators to simulate tornadoes in the lab environment and tested building models in the simulated tornadic wind field, which is similar to wind tunnel testing when quantifying the wind effects induced by straight-line winds. Unfortunately, physical tornado simulators are much less common than straight-line wind tunnels, leading to the lack of research on bluff-body aerodynamics on civil structures under tornadic winds. Considering that it is expensive to conduct experimental testing in physical tornado …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
With the tremendous increase in spending on public projects, contractors need to employ efficient and effective bidding strategies to cope with the competitive bidding environment. Usually, general contractors carry a portion of the work and subcontract other parts to eventually submit a holistic joint bid. This bidding setting is referred to as multistage bidding where subcontractors submit their quotations/bids to the general contractor, after which the general contractor submits a final joint bid for the whole project. In a multistage bidding environment, general contractors may be faced with an increase in the probability of negative or below normal profits. Despite …
