Dynamic amplification factor for moment resisting frames in progressive collapse
… provide requirements for setting up static and dynamic, linear and nonlinear analyses. In particular, a dynamic amplification factor (DAF) of 2 is recommended to account for the dynamic effects when performing a static analysis. Recent studies have determined that the GSA and the UFC guidelines …

Spatial distribution of dynamic amplification in progressive collapse analysis of building frames
The purpose to use Dynamic Application factor is to design and analysis the building and structures more efficient under the progressive collapse where one can only use only the Linear Static Analysis and times the results by the DAF instead of using more complex Linear Dynamic Analysis. It is …

Reliability based live loads for structural assessment of bridges on heavy-haul railway lines
… studies and field measurements of bridge dynamic response and static vertical loads required to compute moments shear for beam-type bridges. The field study of dynamic amplification factors was based on strain measurements on the Olifants bridge located on the heavy-haul iron line in South …

Torsional effects in structures subjected to strong ground motion
The dynamic characteristics and torsional behavior of structures during strong ground motion were investigated; both linear and nonlinear material behavior were considered. Emphasis was placed on the strong torsional coupling associated with the beating phenomenon in the seismic response of …

Dynamic response evaluation of fiber-reinforced composite bridge decks and bridges
… vibrations and may substantially increase the dynamic amplification of induced stress and deflections. Also, a global NDE technique using dynamic characterization is necessary to ensure the long term performance of FRP bridges. Therefore, an extensive study on FRP decks and FRP bridges is …

Stress Response of Tall and Heavy Electronic Components Subjected to Multi-axial Vibration
… higher stresses that are a result of nonlinear dynamic amplification which large components are susceptible to under simultaneous multiaxial excitation, termed multi degree of freedom (MDoF) excitation. However, it is still common practice to conduct vibration durability testing on electronic …

Testing of the suspended vehicle system scale model
… The testing program consisted of both static and dynamic phases. Static tests were used to determine the behavior of the structure to dead loads. Free vibration tests indicated the fundamental structural frequencies, and moving load tests measured the response of the system to moving vehicle …

Structural Robustness of Long-span Cable-Supported Bridges
… such as floods, scours, hurricanes, etc., and dynamic loads such as earthquakes and vehicular impacts. Additionally, recent long-span cable-supported collapse examples show that many bridges suffered progressive collapse when local damage occurred, and they are highly vulnerable to severe …

Behavior and performance of steel moment-framed buildings subject to dynamic column loss scenarios
… single lost column and arrest collapse, but the dynamic and three-dimensional nature of this event prevents simple design-based analysis approaches from providing accurate assessments of collapse resistance. This research employed a set of two prototype steel moment-framed buildings to study …

Consideraciones respecto a los sistemas provisionales de protección de borde
… of the impact defined by the standard, using the dynamic amplification factor in elastic and linear regime, the systems do not comply with the standard requirements. TEPS have been experimentally tested using the Operational Modal Analysis (OMA), obtaining the vibration modes and associated …
