Material based dynamic increase factor models for UHP-FRC under compression and tension
Construction and Building Materials, 2021Abstract Ultra-high performance fiber reinforced concretes (UHP-FRC) exhibit strain rate sensitivity when subjected to dynamic loadings. In recent years, concerns have been raised among researchers that structural effects, such as lateral inertial confinement and frictional confinement at the specimen’s face, could contribute to the strain rate ...

A dynamic system regulation measure for increasing effective capacity: the X-factor theory
Advanced Semiconductor Manufacturing Conference and Workshop, 2003 IEEEI/SEMI, 2003Due to the complex nature of semiconductor manufacturing it is evident that a single scheduling or regulation technique cannot best optimize the system dynamics for reducing cycle time and increasing throughput. The throughput of the system can increase to the effective capacity level of the system.

Fatigue Life Factors and Dynamic Rating Increases for Tapered, Cylindrical and Ball Bearings
SAE Technical Paper Series, 1984<div class="htmlview paragraph">Cleaner steels, advanced manufacturing techniques and the use of modern design methods have justified an increase of dynamic load ratings for cylindrical and tapered roller bearings as well as ball bearings. With the new load ratings, greater emphasis must be placed on the operating factors that influence the ...

Journal of Performance of Constructed Facilities, 2016
AbstractIn recent decades, vulnerability of tall buildings to unforeseen loads induced by progressive collapse has drawn researchers’ attentions. There is a growing tendency among engineers to design tall buildings using complicated structural systems with adventurous load paths that are inconsistent with the existing guideline recommendations ...

Analytical Load and Dynamic Increase Factors for Progressive Collapse Analysis of Building Frames
AEI 2011, 2011Proposed analytical expressions for the load increase factor (LIF) and dynamic increase factor (DIF) are compared with the empirical formulae recommended in the Unified Facilities Criteria (UFC) guidelines UFC 4-023-03 in this study. Static and incremental dynamic analyses are carried out for two moment-resisting frames under sudden column loss.

Effect of Catenary Action on Dynamic Increase Factor in Progressive Collapse Analysis
2019Il collasso progressivo è una modalità di collasso che ha inizio con il danneggiamento prodotto in pochi elementi strutturali da condizioni di carico anomale. Il collasso di tali elementi strutturali in presenza di eventi eccezionali è un fenomeno non lineare e dinamico che mobilita diversi mec-canismi resistenti.
