When Newmark answered Rutgers, Cross looked down his nose at him and commented, “You’ve got a lot of things to unlearn.” In time, the two developed a mutual admiration for each other – and a broad spectrum of interests. Their relationship was based on the interplay and exchange of ideas, not only in engineering but also in a wide range of subjects. They discussed politics, philosophy, art, and the classics with equal relish. Newmark once remarked that his part of the discussions “must have been audible for blocks because Cross was so deaf I had to yell just to be heard.” Newmark received his master’s degree in engineering from UIUC in 1932, the same year he married Anne May Cohen.

  • Effects of Wingwall Configurations on Integral Abutment Bridges
    ABSTRACT Title of Document: EFFECTS OF WINGWALL CONFIGURATIONS ON THE BEHAVIOR OF INTEGRAL ABUTMENT BRIDGES Andreas Paraschos, Doctor of Philosophy, 2016 Dissertation Directed By: Professor Amde M. Amde Department of Civil and Environmental Engineering This research includes parametric studies performed with the use of three-dimensional nonlinear finite element models in order to investigate the effects of cantilever wingwall configurations on the behavior of integral abutment bridges located on straight alignment and zero skew. The parametric studies include all three types of cantilever wingwalls; inline, flared, and U-shaped wingwalls. Bridges analyzed vary in length from 100 to 1200 feet. Soil-structure and soil-pile interaction are included in the analysis. Loadings include dead load in combination with temperature loads in both rising and falling temperatures. Plasticity in the integral abutment piles is investigated by means of nonlinear plasticity models. Cracking in the abutments and stresses in the reinforcing steel are investigated by means of nonlinear concrete models. The effects of wingwall configurations are assessed in terms of stresses in the integral abutment piles, cracking in the abutment walls, stresses in the reinforcing steel of abutment walls, and axial forces induced in the steel girders. The models developed are analyzed for three types of soil behind the abutments and wingwalls; dense sand, medium dense sand, and loose sand. In addition, the models consider both the case of presence and absence of predrilled holes at the top nine feet of piles. The soil around the piles below the predrilled holes consists of very stiff clay. The results indicate that for the stresses in the piles, the critical load is temperature contraction and the most critical parameter is the use of predrilled holes.

  • Mete A. Sözen: a Collection of Personal Remembrances
    Mete A. Sözen: A Collection of Personal Remembrances Mete A. Sözen, Karl H. Kettelhut Distinguished Professor, Emeritus of Civil Engineering, Purdue University died unexpectedly on April 5, 2018, just a few weeks before what would have been his 88th birthday. Mete was in London, England, with his wife Joan visiting their daughter Ayshe and two grandsons when he fell peacefully to sleep. For all of us who knew Mete, this marked the end of an era. Few people have guided and nurtured a field the way Mete led earthquake and structural engineering related to reinforced concrete systems over a period spanning six decades. He had a profound effect on many people and will long be remembered fondly by those who came into contact with him during his career. His impact was so compelling that he had earned the admiration of many generations of students, friends and colleagues and fellow engineers. This article records some of our thoughts about this remarkable man. An only child, Mete was born, according to official birth registry bureau records, on May 22, 1930 in Istanbul Turkey. His family traces its roots to western Georgia from which they had been driven westward during nineteenth century’s numerous armed conflicts in the area, settling first in the city of Ordu on the Black Sea coast and finally in Istanbul. He attended elite primary and secondary schools before enrolling in Robert College, an independent school established in 1863 for the purpose of “giving to its students a thorough education equal in all respects to that obtained at a first-class American college and based upon the same general principles.” Graduating in 1951, he was granted entry into the University of Illinois in Urbana-Champaign where he went on to receive his M.S.

  • Improved Hardy Cross Method for Pipe Networks
    Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 25 December 2018 doi:10.20944/preprints201812.0300.v1 Improved Hardy Cross method for pipe networks Dejan Brkić 1,2,* and Pavel Praks 1,3,* 1 European Commission, Joint Research Centre (JRC), Ispra, Italy 2 IRC Alfatec, Niš, Serbia 3 IT4Innovations, VŠB – Technical University of Ostrava, Ostrava, Czech Republic * Correspondence: [email protected] (D.B.); [email protected] or [email protected] (P.P.) Abstract: Hardy Cross originally proposed a method for analysis of flow in networks of conduits or conductors in 1936. His method was the first really useful engineering method in the field of pipe network calculation. Only electrical analogs of hydraulic networks were used before the Hardy Cross method. A problem with the flow resistance versus the electrical resistance makes these electrical analog methods obsolete. The method by Hardy Cross is taught extensively at faculties and it still remains an important tool for analysis of looped pipe systems. Engineers today mostly use a modified Hardy Cross method which threats the whole looped network of pipes simultaneously (use of these methods without computers is practically impossible). A method from the Russian practice published during 1930s, which is similar to the Hardy Cross method, is described, too. Some notes from the life of Hardy Cross are also shown. Finally, an improved version of the Hardy Cross method, which significantly reduces number of iterations, is presented and discussed. Keywords: Hardy Cross method; Pipe networks; Piping systems; Hydraulic networks; Gas distribution. 1. Introduction Hardy Cross solved the problem of distribution of flow in networks of pipes in his article “Analysis of flow in networks of conduits or conductors” [1] published on November 13th 1936.

  • Rascacielos a La Italiana. Construcción De Gran Altura En Los Años Cincuenta Y Sesenta
    Informes de la Construcción Vol. 72, 558, e342 abril-junio 2020 ISSN-L: 0020-0883 https://doi.org/10.3989/ic.71572 Italian style skyscrapers. High-rise construction in the fifties and sixties Rascacielos a la italiana. Construcción de gran altura en los años cincuenta y sesenta G. Capurso (*) ABSTRACT In the fifties and sixties, while Italian engineering was receiving important international awards, the theme of the tall building attracted the attention of the best architects. They made it a field of design experimentation, immediately sensing how the strategic use of the structure could revolutionize the already stereotyped image of the all-steel and glass towers proposed by the International Style. Gio Ponti, Luigi Moretti and the BBPR thus created formidable partnerships with Pier Luigi Nervi and Arturo Danusso, the most active engineers in the field of skyscraper design. The result was at least three masterpieces, among the works created in those years: the Velasca tower and the Pirelli skyscraper in Milan and the Stock Exchange tower in Montreal, which, at the time of its completion, also marked the record for the highest reinforced concrete building in the world. Keywords: Italian Engineering, skyscrapers, structures, reinforced concrete, Pier Luigi Nervi, Arturo Danusso, Italian Style, International Style, Construction History, SIXXI research project. RESUMEN En los años cincuenta y sesenta del siglo XX, mientras la ingeniería italiana recibía importantes premios internacionales, el diseño de los edificios en altura atraía la atención de los mejores arquitectos. Estos entendieron inmediatamente lo mucho que el empleo estratégico de la estructura habría podido revolucionar la ya de por sí estereotipada imagen de la torre de acero y vidrio propuesta por el Estilo Internacional, y lo convirtieron en un campo de experimentación.

  • Leonard K. Eaton Hardy Cross and the “Moment Distribution Method”
    Leonard K. Hardy Cross and Eaton the “Moment Distribution Method” Leonard K. Eaton resurrects the reputation of Hardy Cross, developer of the “moment distribution method” and one of America’s most brilliant engineers. The structural calculation of a large reinforced concrete building in the nineteen fifties was a complicated affair. It is a tribute to the engineering profession, and to Hardy Cross, that there were so few failures. When architects and engineers had to figure out what was happening in a statically indeterminate frame, they inevitably turned to what was generally known as the “moment distribution” or “Hardy Cross” method. Although the Cross method has been superseded by more powerful procedures such as the Finite Element Method, the “moment distribution method” made possible the efficient and safe design of many reinforced concrete buildings during an entire generation. Introduction In his paper “The Influence of Mathematics on the Development of Structural Form” in Nexus II: Architecture and Mathematics, Holger Falter comments on the difficulty of calculating statically indeterminate frames of reinforced concrete. He remarks, “Forming hinges was simple with iron, but difficult with reinforced concrete. It created statically indeterminate frames continuing through several spans, a difficulty surmountable only by using analytical methods” [Falter 1998:61]. He emphasizes the change from graphic to analytical statics and concludes that, “Only a limited number of statically indeterminates could be solved with these new procedures, which is probably the reason for the mostly simple structures, causing as little calculating effort as possible” [Falter 1998: 61]. Whi1e I am in general agreement with Falter’s account, I would like to offer an emendation and in so doing resurrect the reputation of Hardy Cross, one of America’s most brilliant engineers.

    NATIONAL HISTORIC CONTEXT AND SIGNIFICANCE OF THE GENERAL SULLIVAN BRIDGE DOVER, NEW HAMPSHIRE Written by Richard M. Casella Engineering and Architectural Historian Historic Documentation Company Portsmouth, Rhode Island For Preservation Company Kensington, New Hampshire and New Hampshire Department of Transportation Concord, New Hampshire October, 2005 NATIONAL HISTORIC CONTEXT AND SIGNIFICANCE OF THE GENERAL SULLIVAN BRIDGE Summary Research has identified and defined the early development period of continuous truss highway bridges in the United States as being from 1927 to 1937. This period was preceded by a ten-year period beginning in 1917 during which time the continuous truss railroad bridge was developed. The General Sullivan Bridge is one of four major bridges of the same type, style and time period designed by the firm of Fay, Spofford and Thorndike, that as a group significantly influenced future continuous truss highway bridge design in the areas of technology, aesthetics and construction methods. Fay, Spofford and Thorndike (FS&T) remains in business today and since forming in 1914 established itself as a bridge engineering firm of national importance. A significant advancement in the technology and aesthetics of continuous truss highway bridge design came with the building of the Lake Champlain Bridge and the three other bridges in which the original design was refined and improved upon. The Lake Champlain Bridge, completed in 1928, was the third major continuous truss highway bridge built in the U.S. It was a highly innovative and aesthetic design that placed the roadway above the side trusses and through an arched center truss. The design was called "ingenious" for its deck layout that "provided the necessary clearance at mid-span with such economy in the approaches." 1 The second bridge of the group was the Little Bay Bridge, completed in 1934 and later renamed the General Sullivan Bridge.
