Perimeter protection is an important physical protection approach for buildings and infrastructures, which is also regarded as the first line of protection. Vehicle borne improvised explosive devices (VBIED) have been recognized as a major design threat by many government agencies for years, since they have been so extensively used in past terrorist attacks against critical buildings and infrastructures. Preventing unauthorized vehicles from approaching a protected area with vehicle barriers installed in perimeter of the buildings and infrastructures would consequently reduce blast and debris threats. The history of test certification standard for vehicle barriers is briefly reviewed. The research achievements on anti-ram bollards, one type of vehicle barriers, in the fields of crash test, numerical simulation, and design theory are presented. The remaining problems and deficiencies of the research are pointed out and the corresponding proposals are put forward. Finally, some further research works on anti-ram bollards are proposed.

This paper describes a historic civil engineering bridge site on the Rideau Canal. The history of the site is traced from 1882, when the first bridge was built, to the time of the existing modern structure. Most of the bridges were of the movable type, being either swing or vertical lift structures. The present bridge, which was built in 1980–1981, was designed taking into consideration many of the historic features of past bridges especially the latter bridge, which was built in 1915–1917. Various technical features of the new bridge enhance one's perspective of modem design methods when they are compared with past state-of-the-art methods. The resulting bridge is a functional structure that maintains the heritage of the historic bridges and at the same time blends with the environment.

In recent years the discipline of Architecture in Master of Civil Engineering at FEUP, has been showing to future engineers the common territory of architecture and civil engineer. By building technologies, particularly structural systems, the pedagogic methodology shows this basilar triad, construction technology / structural system / architectural form, for the understanding of architectural grammar. In the lectures, with concrete cases in the history of architecture addresses the integrated design methodology. In practical classes, the analysis of specific projects, the preparation of drawings and even the preparation of models, shows the students the construction system in the studio and in the site, through the design tools. This article seeks to present the developed experience of the recent years in this course, in order to contribute to the increasingly urgent intersection of Architecture and Engineering.

Introduction. The gradual progressive evolvement of civil engineering as a science was nurtured by numerous discoveries, errors and regularities contributed by philosophers, mathematicians, engineers, architects, and researchers focused on versatile areas of knowledge. The author analyzes the transformation of civil engineering as a science since ancient times, as well as its dependence on historical events, territoriality, and discoveries. The objective of the research, covered by the article, consists in the detailed analysis of the history of civil engineering and the prognostication of its future development pattern. Materials and methods. The author employed systematization, benchmarking, and theoretical generalization of the information collected from literary sources. Results. The author has analyzed a number of Russian and foreign literary sources covering the formation and evolution of the civil engineering science, beginning with the works of ancient thinkers and philosophers and ending with the works of contemporary researchers. The author breaks down the history of analysis/design of buildings/structures into four development phases that have evolved into the present-day design procedure. The author also provides detailed information on ancient scholars, starting from those who lived in the second millennium B.C., and their contribution into the theory of building design. She highlights the most important works written by ancient philosophers and mathematicians all over the world, particularly those who influenced the development of the design theory. The author provides examples and photos of still-standing unique buildings and structures that date back to each development phase. Every step of civil engineering development is illustrated by buildings and descriptions of their constructions. The author also analyzes the most prominent attainments made in the field of structural mechanics and design of buildings at each development stage. She has tracked the evolvement of civil engineering since the inception of written languagest. Conclusions. The author analyzes the prospects for the development of the civil engineering science with account for the most recent reports issued by the Russian Academy of Architecture and Construction Sciences.

In the Cold War, “development” was a catchphrase that came to signify progress, modernity, and economic growth. Development aid was closely aligned with the security concerns of the great powers, for whom infrastructure and development projects were ideological tools for conquering hearts and minds around the globe, from Europe and Africa to Asia and Latin America. This book provides a global history of development, drawing on a wealth of archival evidence to offer a panoramic and multifaceted portrait of a Cold War phenomenon that transformed the modern world. Taking readers from the aftermath of the Second World War to the tearing down of the Berlin Wall, the book shows how development projects altered local realities, transnational interactions, and even ideas about development itself. The book shines new light on the international organizations behind these projects—examining their strategies and priorities and assessing the actual results on the ground—and it also gives voice to the recipients of development aid. It shows how the Cold War shaped the global ambitions of development on both sides of the Iron Curtain, and how international organizations promoted an unrealistically harmonious vision of development that did not reflect local and international differences. The book presents a global perspective on Cold War development, demonstrating how its impacts are still being felt today.

Subject. The article addresses the history of development and provides the criticism of existing criteria for aggregate social welfare (on the simple exchange economy (the Edgeworth box) case). Objectives. The purpose is to develop a unique classification of criteria to assess the aggregate social welfare. Methods. The study draws on methods of logical and mathematical analysis. Results. The paper considers strong, strict and weak versions of the Pareto, Kaldor, Hicks, Scitovsky, and Samuelson criteria, introduces the notion of equivalence and constructs orderings by Pareto, Kaldor, Hicks, Scitovsky, and Samuelson. The Pareto and Samuelson's criteria are transitive, however, not complete. The Kaldor, Hicks, Scitovsky citeria are not transitive in the general case. Conclusions. The lack of an ideal social welfare criterion is the consequence of the Arrow’s Impossibility Theorem, and of the group of impossibility theorems in economics. It is necessary to develop new approaches to the assessment of aggregate welfare.
