RISOverstrength and Ductility Factors for Steel Frames Designed According to BS 5950
Publisher: American Society of Civil Engineers
Abstract: Buildings sited outside the seismic zones such as those in Singapore are not designed for seismic loads. However, the buildings in these regions vibrate due to tremors caused by faults in Sumatra, Indonesia. Therefore, in ...
CAD-Integrated Excavation and Pipe Laying
Publisher: American Society of Civil Engineers
Abstract: Excavation and, in particular, trenching using backhoes represents a hazardous working environment for workers. The hazards include trench walls that collapse, the accidental drop of heavy objects into the opening, excavators ...
Autofrettage and Reautofrettage of a Spherical Pressure Vessel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There is a numerical procedure for modeling autofrettage of thick-walled cylinders that incorporates the Bauschinger effect as a function of prior plastic strain and Von Mises’ yield criterion. ...
Soil-Structure Interaction and Pulse Shape Effect on Structural Element Damage to Blast Load
Publisher: American Society of Civil Engineers
Abstract: The mode approximation method (MAM) is an effective approach when analyzing dynamic structural responses and damages to blast loading. The pressure-impulse (P-I) diagram generated from the MAM provides an efficient and ...
Design and Performance Evaluation of a Trigeneration System Incorporating Hydraulic Storage and an Inverted Brayton Cycle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To bring the economic benefit of trigeneration to small-scale users without incorporating expensive components, an inverted Brayton cycle (IBC) is employed, which makes use of the expander section ...
Mechanical Properties of Titania-Doped Yttria Stabilized Zirconia (TiYSZ) for Use as Thermal Barrier Coating (TBC)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Representative samples of yttria stabilized zirconia (7YSZ) co-doped with varying concentrations of TiO2 were fabricated using plasma spraying. Samples were sintered in order to minimize porosity ...
Simplified Damage Assessment Method for Buried Structures against External Blast Load
Publisher: American Society of Civil Engineers
Abstract: Decoupling of soil-structure interaction is applied to analyze buried structure damage due to external blast load. The structural element under analysis is assumed to deform as a simply supported rigid-plastic beam. Shear ...
Simultaneous Measurement of Three-Dimensional Soot Temperature and Volume Fraction Fields in Axisymmetric or Asymmetric Small Unconfined Flames With CCD Cameras
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonintrusive measurement technique is presented numerically for simultaneous measurement of three-dimensional (3D) soot temperature and volume fraction fields in the axisymmetric or asymmetric ...
Water Inflow Prediction during Heavy Rain While Tunneling through Karst Fissured Zones
Publisher: American Society of Civil Engineers
Abstract: A new method is proposed for water inflow prediction during heavy rain while tunneling through karst fissured zones. The proposed prediction method is a semianalytical and seminumerical method. First, an analytical ...
TBM–Block Interaction during TBM Tunneling in Rock Masses: Block Classification and Identification
Publisher: American Society of Civil Engineers
Abstract: A new block-classification method for tunnel construction using a tunnel-boring machine (TBM) to capture the geometrical and mechanical transformation of rock blocks in the course of TBM excavation is proposed in this ...
