Abstract: There is considerable uncertainty regarding both the timing and contributions of various individuals to the development of reinforced concrete flat slabs in the United States. The work of George M. Hill and the patent of ...

Abstract: The construction of the Battery-Joralemon Street Tunnel is described. Built between 1903 and 1907, it was the first subway tunnel placed in service under the East River between Manhattan and Brooklyn. Both heading-and-bench ...

Abstract: The design, fabrication, erection, and performance of an iron railroad bridge built in 1863–65 at Ashtabula, Ohio, is examined. The bridge collapsed after 11 years of service, very likely due to fatigue and brittle fracture ...

Abstract: A suitable filter response is defined that allows studies of the effects of excitation bandwidth on the responses of geometrically nonlinear dynamic systems. For such a random excitation, as the bandwidth approaches zero, ...

Abstract: Results of a bifurcation analysis of a geometrically nonlinear cable truss are reported. Additive antisymmetric harmonic excitation and parametric symmetric harmonic excitation are used. For antisymmetric excitation, ...

Abstract: Equations of motion for a plane, nonlinear prestressed truss are expressed in terms of six generalized coordinates. Three coordinates define a dominant centrally symmetric vibration mode. The dominant coordinate of that mode,

Abstract: The long‐term durability of steel‐to‐steel bonds is affected by the ingress of water in a bondline. Sorption of water by an adhesive changes its physical properties and degrades the adhesion between the adhesive and the ...

Abstract: The influence of the American engineer George Washington Whistler on the design of the St. Petersburg-Moscow Railway, called the Nikolaev Railway, is discussed. The line, built between 1842 and 1851 and approximately ...

Abstract: The static and dynamic behavior of a cable dome was studied by testing a 1/50 scale model. Three different pretension levels were considered. The static response of the model under a symmetric and an antisymmetric loading ...
