Formulation and Validation of a Nonlinear Shell Element for the Analysis of Reinforced Concrete and Masonry Structures
… structures. The accurate determination of the nonlinear response of reinforced concrete and reinforced masonry (RC/RM) walls subjected to lateral loading is of uttermost importance for ensuring the safety of the built environment. Analytical models provide a cost efficient and comprehensive …

Shell finite elements, with applications in biomechanics
… those in the literature. Using the geometric and material parameters given in earlier studies of prosthetic aortic valve leaflets, the shell solution algorithm was used to simulate a leaflet with and without transverse isotropy. The deformed leaflet behaved as expected for a diastolic state and …

Characterization and Development of General Material Models for Use in Modeling Structures Bonded with Ductile Adhesives
Structural adhesives are materials that are capable of bearing significant loads in shear, and sometimes tension, over a range of strains and strain rates. Adhesively bonded structures can dissipate large amounts of mechanical energy and can be lighter and more efficient than many bolted or …

Performance-based earthquake engineering with the first-order reliability method
… the applicability of FORM to the linear and nonlinear finite-element structural models under static and dynamic loading is investigated. The case studies indicate that FORM is applicable for linear and nonlinear static problems. Strategies are proposed to circumvent and remedy potential …

Behavior and performance of steel moment-framed buildings subject to dynamic column loss scenarios
… United States. Three-dimensional finite element models were constructed to model the buildings using shell elements and incorporating the steel deck and composite concrete slab floor system. Nonlinear material models were used along with simplified component models for beam and girder …

Simulation of the In-plane and Out-of-plane Seismic Performance of Nonstructural Partition Walls
… data is used to propose and calibrate analytical nonlinear material models for the connections in OpenSees. Subsequently, the connection models are employed to propose a novel detailed and yet computationally efficient modeling methodology for nonstructural partition walls. In this methodology, …
