Considering hydrostatic pressure as the only external load on an arch dam, the influence of the reservoir elevation and the elastic deformability of the foundations is investigated using...

Random Vibration of a Beam Column
The lateral displacement of a vertical cantilever beam subjected to an axial load acting at the free end and under a random horizontal motion of the clamped end is evaluated. This is one...

Analysis of Continuous Folded Plate Surface
A general method of analysis of single or continuous span folded plate surfaces, with general end conditions, for any loading condition is developed. Within the limitations of the assumptions,...

Simultaneous Relative Orientation of Multiple Cameras
There are two groups of solutions to the problem of analytical aerotriangulation. The first group uses a cantilever extension technique based on independent triangulation of two-photograph...

Lumping of Mass in Calculating Vibration Response
Analytical results are presented in which the vibration response of a uniform Bernoulli-Euler cantilever beam carrying a tip mass is compared with that of a weightless beam supporting...

Deflection of Circular Curved I-Beams
The analysis of continuous curved I-beams requires the prediction of deflections for various loadings on the structure. The simplest structural element is the cantilever; therefore, the...

Response of Structures to Triangular Pulse Loading
Two nomographic charts were presented for obtaining the response of a single-degree-of-freedom linear system subjected to an initial-peak, triangular force-pulse. The instantaneous amplification...

Pan American Passenger Terminal at Idlewild Airport
The design of a passenger terminal for operation exclusively by jet aircraft posed a number of unusual design problems. These were increased by the requirement of having a cantilevered...
