The object of this study is to examine the process of the birth and transformation of civil engineering education as well as of modern civil engineers, called 'State noblesse', in the state engineer groups of France. For this, we will look into the background of founding the civil engineer corps and the civil engineering school, the transformation process of the civil engineering school into the applied school of Ecole Polytechnique, the activities of civil engineers in the industrialization process, and finally the organization and identity of the civil engineer group.

This paper deals with the early history of the British civil engineers as a group in terms of where they originated from, how they emerged as a profession in the British society during the First Industrial Revolution, and when they began to be educated at the formal higher education institution. Eventually this paper intends to seek for something like a British style of civil engineering.

This paper examines the birth of civil engineers in the United States. Unlike the advanced some European countries such as Great Britain or France, as a new nation America had to import high-tech technologies from them. In the process of transplantation she had mixed up the civil engineering of British style with French's. As a result, the training of the civil engineers in America had developed in various ways.

이 논문에서는 산업체 근무자에 대한 설문조사를 통해 우리나라 공학교육의 문제점을 파악하고자 하였다. 이를 위해 토목공학 분야에 대해서는 공학교육인증원에서 요구하는 학습성과를 기준으로 설문지를 작성한 후 직접 설문조사를 실시하고 그 내용을 분석하였으며, 화학공학 및 전자공학 분야에 대해서는 문헌조사를 통해 확보한 최근의 조사 결과를 이용하여 분석하였다. 설문조사 결과 3개 분야 모두 산업체 요구수준에 비해 대학졸업생의 수준이 절반에도 못 미치는 것으로 나타나 공학교육의 개선이 시급한 것으로 분석되었다.

Hollow structural section (HSS) columns have been increasingly popular due to their structural and architectural merits. However, practical difficulty lies in developing proper connections. The through-diaphragm connections are considered as suitable connection type that is widely adopted in Asian countries. However, the stress concentration occurs at the location connecting through-diaphragm and steel beam. Furthermore, the actual load path from the beam flange is not uniformly transferred to the HSS column as conventionally assumed. In this paper, tensile tests were further conducted on three additional specimens with beam flange plate to evaluate the load versus displacement response. The load-displacement curves, yield and ultimate capacity, ductility ratio were obtained. Furthermore, the strain development at different loading levels was discussed comprehensively. It is shown that the studied connection configuration significantly reduces the stress concentration. Meanwhile, simplified trilinear load-displacement analytical model for specimen under tensile load was presented. Good agreement was found between the theoretical and experimental results.

To study the working mechanism and size effect of an innovative dovetail UHPC joint originated from the 5th Nanjing Yangtze River Bridge, a large-scale testing subject to negative bending moment was conducted and compared with the previous scaled specimens. The static responses, i.e., the crack pattern, failure mode, ductility and stiffness degradation were analyzed. It was found that the scaled specimens presented similar working stages and working mechanism with the large-scale ones. However, the post-cracking ductility and relative stiffness degradation all decrease with the enlarged length/scale, apart from the relative stiffness after flexural cracking. The slab stiffness at the flexural cracking stage is 90% of the initial stiffness while only 24% of the initial stiffness reserved in the ultimate stage. Finite element model (FEM) was established and compared with the experiments to verify its effectiveness in exploring the working mechanism of the innovative joint. Based on this effective method, a series of FEMs were established to further study the influence of material strength, pre-stressing level and ratio of reinforcement on its deflection-load relationship. It is found that the ratio of reinforcement can significantly improve its load-carrying capacity among the three major-influenced factors.

Local buckling can be ignored for hot-rolled ordinary strength steel equal angle compression members, because the width-to-thickness ratios of the leg don't exceed the limit value. With the development of steel structures, Q420 high strength steel angles with the nominal yield strength of 420 MPa have begun to be widely used in China. Because of the high strength, the limit value of the width-to-thickness ratio becomes smaller than that of ordinary steel strength, which causes that the width-to-thickness ratios of some hot-rolled steel angle sections exceed the limit value. Consequently, local buckling must be considered for 420 MPa steel equal angles under axial compression. The existing research on the local buckling of high strength steel members under axial compression is briefly summarized, and it shows that there is lack of study on the local buckling of high strength steel equal angles under axial compression. Aiming at the local buckling of high strength steel angles, this paper conducts an axial compression experiment of 420MPa high strength steel equal angles, including 15 stub columns. The test results are compared with the corresponding design methods in ANSI/AISC 360-05 and Eurocode 3. Then a finite element model is developed to analyze the local buckling behavior of high strength steel equal angles under axial compression, and validated by the test results. Following the validation, a finite element parametric study is conducted to study the influences of a range of parameters, and the analysis results are compared with the design strengths by ANSI/AISC 360-05 and Eurocode 3.
