RISUnsteady Wire Sweep Due to Transfer Molding in a 160L QFP Package
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wire sweep has been recognized as one of the major defects in encapsulation of electronic components by transfer molding. The phenomenon is very complicated as it is sensitive to a large ...
Service Performance of Long-Span Lightweight Aggregate Concrete Box-Girder Bridges
Publisher: American Society of Civil Engineers
Abstract: This paper provides background on the use of lightweight aggregate concrete in long-span bridges. Observed time-dependent deflection of long-span lightweight aggregate concrete box-girder bridges is highlighted. The paper ...
Wire Sweep Due to Transfer Molding in a 160L QFP Package Under Steady-State Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wire sweep has been recognized as a critical process defect which can result in device failure. The phenomenon is very complicated as it is sensitive to a large number of parameters. In this ...
Flexural Strength and Ductility of Extended Pile-Shafts. I: Analytical Model
Publisher: American Society of Civil Engineers
Abstract: An analytical model, based on the commonly used equivalent cantilever concept, is developed for assessing the local ductility demand of a yielding pile-shaft when subjected to lateral loading. For elastic response of the ...

Publisher: American Society of Civil Engineers
Abstract: This paper provides background on the use of lightweight aggregate concrete in long-span bridges. Observed time-dependent deflection of long-span lightweight aggregate concrete box-girder bridges is highlighted. The paper ...
Sectional Depth of Prestressed Concrete Beams with Excess Capacity
Publisher: American Society of Civil Engineers
Abstract: In this paper, the requirements for the sectional depth of prestressed concrete beams satisfying the permissible stress limits are examined. An explicit expression for the member depth is derived in terms of three geometric ...
Bridge Deck Replacement of Posttensioned Concrete Box-Girder Bridges
Publisher: ASCE
Abstract: This paper studies the feasibility of replacing damaged deck of posttensioned concrete box-girder bridges without the use of falsework to support the superstructure span. Parameters of the study included straight, curved, ...
Reexamination of the Vibrational Period of Coupled Shear Walls by Differential Transformation
Publisher: American Society of Civil Engineers
Abstract: In multistory buildings, coupled shear walls are frequently used as the main lateral load resisting system, the seismic design of which requires some knowledge of their periods of vibration. Although the vibrational ...
Waiting Period for Closure Pours in Bridge Widening or Staged Construction
Publisher: American Society of Civil Engineers
Flexural Strength and Ductility of Extended Pile-Shafts. II: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: Results of an experimental program investigating the lateral strength and ductility capacity of reinforced concrete piles are presented. Four full-scale reinforced concrete piles with details representative of the current ...
