“…Advanced FEM software such as ABAQUS and ANSYS were not adopted as they are rarely used by most industry professionals for new curtain wall design. While they have been used for research [15,16,22,35,39], Memari et al [7,8] found that commercial software SAP2000 can be equally comparable in most performance levels of curtain walls under loading. Additionally, SAP has a low boundary to learn with both linear and non-linear capabilities and can be more directly integrated into the full building design [50].…”

“…Experimental testing can be used to calculate appropriate glass-panel failure states during design review. In addition to its aforementioned successful use in predicting the wind resistance of a given glass panel, FEM has also been used successfully to predict local stresses caused by wind-borne debris impact in glass [4,[13][14][15], blast loading [16], modal analysis of laminated glass [17], glass tempering [18,19], and thermal and residual stresses in annealed glass and other settings for unique loadings [20][21][22].…”

In the cyclic racking evaluation of curtain wall systems, physical testing with instrumentation is the standard method for collecting performance data by most design professionals. The resulting testing of full-scale mockups can provide many types of data, including load and displacement values at different stages of loading through failure. While this type of data is valuable for product/system development/fabrication and design, such data can also provide a means for simulation validation of the curtain wall cyclic performance under simulated earthquake loading. Once the simulation study is validated using the test results, then parametric studies by designers can be conducted with greater ease, ideally with commercial software packages, without the need for testing. For the results of this research study, a practical industry formulated finite element modeling (FEM) approach was used to predict the performance of the curtain wall mockups. Here, unitized four-sided structural sealant glazing (4SSG) curtain wall system mockups that incorporate a re-entrant corner were subjected to cyclic racking displacements per the American Architectural Manufacturers Association (AAMA) 501.6 Structural Sealant protocol. System performances, including displacements, were obtained from the FEM study and used to calculate the effective shear strain of the structural silicone and the drift capacity of the system. This paper describes the details of the techniques developed for FEM, the analysis results, and shows an example application of the numerical modeling approach for mockups with racking test results available. The goal of this modeling approach was to create and test methods that practicing consulting engineers can quickly conduct in their offices on common commercially available software often available to them.

“…In recent years, a large number of experimental [2][3][4][5][6][7][8][9][10][11], analytic [12][13][14][15][16], and numerical studies have been devoted to the fracture of soda lime glass. Nie and Chen [2][3][4][5] conducted SHPB experiments to study the effect of the shear stress, mechanical confinement, and temperature on the strength of glass under dynamic loading.…”

“…Further research shows that not only the compressive strength but also the tensile strength could increase with the increase of strain rate [8,11]. Ji and Dharani [15] developed analytic approaches to simulate the damage probability in laminated glass subjected to low velocity small missile impacts. Dharani et al [14] proposed a two-parameter Weibull distribution to characterize the cumulative probability of inner glass ply breakage.…”

In this paper, rate-dependent cohesive zone model was established to numerical simulate the fracture process of soda-lime glass under impact loading. Soda-lime glass is widely used in architecture and automobile industry due to its transparency. To improve the accuracy of fracture simulation of soda-lime glass under impact loading, strain rate effect was taken into consideration and a rate-dependent cohesive zone model was established. Tensile-shear mixed mode fracture was also taken account. The rate-dependent cohesive zone model was implemented in the commercial finite element code ABAQUS/Explicit with the user subroutine VUMAT. The fracture behavior of a monolithic glass plate impacted by a hemispherical impactor was simulated. The simulation results demonstrated that the rate-dependent cohesive zone model is more suitable to describe the impact failure characteristics of a monolithic glass plate, compared to cohesive zone model without consideration of strain rate. Moreover, the effect of the strain rate sensitivity coefficient C, the mesh size of glass plate and the impact velocity on the fracture characteristics were studied.

Investigation of impact fracture behavior of automobile laminated glass by 3D discrete element method

A three-dimensional discrete element model of laminated glass plane is presented and a 3D numerical analysis code, which can simulate the impact fracture behavior of automobile laminated glass, is developed. The impact process of a single glass plane and a laminated glass plane are calculated in the elastic range by the code. Comparing its results with those calculated by the commercial FEM code LS-DYNA in the same condition, the validity of the 3D laminated glass model and the 3D discrete element method are proved. Furthermore, the impact fracture process of a single glass plane and a laminated glass plane are simulated respectively. The entire failure processes in detail are presented. By comparing the impact force and reduction of kinetic energy of impact body between those two models, the numerical method is applied to demonstrate the advantage of laminated glass in passenger's safety.
