RISCharacterization of Three-Mode Combination Internal Resonances in Electrostatically Actuated Flexible–Flexible Microbeams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear intermodal coupling based on internal resonances in MEMS resonators has advanced significantly over the past two decades for various real-world applications. In this study, we demonstrate the existence of various ...
Risk Reduction by Automatic Seismic Shutoff

Seismic Response of Soil-Supported Unanchored Liquid-Storage Tanks
Publisher: American Society of Civil Engineers
Abstract: A systematic study is made of the effects of base uplifting on the seismic response of cylindrical liquid-storage tanks that are supported directly on flexible soil foundations. First, a detailed investigation is made of ...
Analysis of Different Test Methods for Quantifying Rutting Susceptibility of Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: Various rutting susceptibility parameters for unmodified and modified bitumen were studied at three different temperatures of 40, 50, and 60°C. Wheel rut testing was also conducted on three different bituminous mixes at ...
Seismic Strengthening of Liquid-Storage Tanks with Energy-Dissipating Anchors
Publisher: American Society of Civil Engineers
Abstract: The seismic performance of liquid-storage steel tanks can be improved by anchoring them to their foundations with energy-dissipating devices rather than with conventional anchors. Case studies of two tanks are presented—one ...
Assembly Free Large Scale Modal Analysis on the Graphics Programmable Unit
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Popular eigensolvers such as blockLanczos require repeated inversion of an eigenmatrix. This is a bottleneck in largescale modal problems with millions of degrees of freedom. On the other hand, the classic Rayleigh–Ritz ...
Large Scale Finite Element Analysis Via Assembly Free Deflated Conjugate Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Largescale finite element analysis (FEA) with millions of degrees of freedom (DOF) is becoming commonplace in solid mechanics. The primary computational bottleneck in such problems is the solution of large linear systems ...
Return Period of Recorded Ground Motion
Publisher: American Society of Civil Engineers
Abstract: Ground motions recorded during earthquakes are often used to assess the seismic performance of structures affected by those ground motions. However, it is necessary to first establish the return period of the recorded ...
Analysis of Different Test Methods for Quantifying Rutting Susceptibility of Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: Various rutting susceptibility parameters for unmodified and modified bitumen were studied at three different temperatures of 40, 50, and 60°C. Wheel rut testing was also conducted on three different bituminous mixes at ...
Laboratory Study on Moisture Susceptibility of Dense Graded Mixes
Publisher: American Society of Civil Engineers
Abstract: Moisture damage is the degradation of the mechanical properties of the material attributable to the presence of moisture in its microstructure. To enhance the life of bituminous pavements, it is necessary to understand ...
