Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...
Fault Identification by Seismic Impact Load Techniques
The propagation of seismic waves generated by impact loading across a normal fault in carbonate rock was investigated by the seismic refraction technique. The field records were reduced,...
Stability and Limit Loads of Steel Space Trusses
An investigation of the behavior of cold-formed steel space truss structures, under the interaction of local, member, and overall buckling is described. A Finite Element computer program...
Buckling of Thin-Walled Members by p-Version of FEM
P-Version of the finite element method (FEM) is used for one-D and three-D modeling of thin-walled open sections and axial compressive load. Equal angle and channel sections are used for...
Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...
Frame Stability
The Chapter on Frame Stability of the Fourth Edition of the SSRC Guide provides guidance on use of several stability design procedures. These include Critical Load Concept, Second-Order...
Dynamic Fracture Toughness of Rail Steels
As new premium alloy rail steels exhibit increased wear resistance and as track lubrication is used, the failure mode for rails is shifting from wear to fatigue. Elastodynamic finite element...
Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...
Sewer-Septic Tank Hybrid Promises Savings
Until recently the only options for sewage were the septic tank/leach field or conventional sewers. In some cases a hybrid of the two, called the septic tank/effluent drain, is less costly...
Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...
