5、年民主革命的幾年前，土木工程行業(yè)發(fā)生了一次深刻的教育系統(tǒng)的變革。一個(gè)培養(yǎng)新型研究人員的大型機(jī)構(gòu)成立了，這一機(jī)構(gòu)專門培養(yǎng)沒有被各大學(xué)和公共實(shí)驗(yàn)室涵蓋的研究人員并提供出國(guó)學(xué)習(xí)的資金。里斯本技術(shù)大學(xué)工程學(xué)院是一高級(jí)技術(shù)研究所（IST），它是最早受益于這一大型機(jī)構(gòu)的機(jī)構(gòu)之一，并且鋼結(jié)構(gòu)被明智地確定為土木工程學(xué)院新型職工培訓(xùn)的主要要求。</p><p>　　由于正在進(jìn)行的殖民戰(zhàn)爭(zhēng)，我在剛剛服完長(zhǎng)期的兵役之后，獲得了一筆助學(xué)

6、金是我可以在皇家學(xué)院學(xué)習(xí)鋼結(jié)構(gòu)課程。我在大學(xué)期間接受的建筑結(jié)構(gòu)方面的培訓(xùn)是很充分的，但是正是由于幾何非線性和材料非線性與混凝土結(jié)構(gòu)聯(lián)系不大，大學(xué)的教學(xué)在這兩方面是不足的。鋼結(jié)構(gòu)的復(fù)雜性深深吸引著我，我希望可以在倫敦進(jìn)行進(jìn)一步的的學(xué)習(xí)取得更高的學(xué)位，但是祖國(guó)大學(xué)的變革需要我回國(guó)。我回去了，還錯(cuò)誤的認(rèn)為我有能力在里斯本建立博士點(diǎn)。然而，對(duì)于葡萄牙年輕的一代來說，1975年是振奮人心的一年并不適合啟動(dòng)一項(xiàng)研究項(xiàng)目，1976年初，我申請(qǐng)回到皇家

15、在葡萄牙的主要土木工程機(jī)構(gòu)建立鋼鐵研究集團(tuán)。這個(gè)目標(biāo)已經(jīng)實(shí)現(xiàn)，并且在里斯本州大學(xué)、科英布拉大學(xué)、阿威羅大學(xué)、貝拉內(nèi)政部大學(xué)、布拉干薩大學(xué)和波爾圖大學(xué)都在本科和碩士的課程中加入了鋼結(jié)構(gòu)課程，該協(xié)會(huì)還資助最好的學(xué)生鋼結(jié)構(gòu)項(xiàng)目。</p><p>　　cmm的新主席路易斯蒙斯羅席爾瓦是科英布拉土木工程系教授，他是歐洲最杰出的年輕鋼鐵專家之一，而且是畢業(yè)于英國(guó)皇家理工學(xué)院的博士。在他的領(lǐng)導(dǎo)下尤其是在大學(xué)教育的支持下，我相信

16、cmm將會(huì)進(jìn)入一個(gè)新的上升階段。事實(shí)上，在cmm的支持下，我們共同提出了一個(gè)新的碩士學(xué)位的鋼結(jié)構(gòu)和復(fù)合結(jié)構(gòu)的課程。它從2005年由高級(jí)技術(shù)研究所（IST）和科英布拉聯(lián)合舉辦。它旨在很快成為一門歐洲重要的課程。</p><p>　　早在19世紀(jì)80年代葡萄牙的鋼材僅用于不重要的建筑中，發(fā)展到今天，它被用于一些高層建筑和橋梁（鋼結(jié)構(gòu)和復(fù)合結(jié)構(gòu)）中。我自豪地認(rèn)為，cmm及其對(duì)新設(shè)計(jì)人員的培養(yǎng)極大的促進(jìn)了這一增長(zhǎng)，但是其

17、他歐洲國(guó)家的原材料價(jià)格調(diào)整及公眾對(duì)鋼結(jié)構(gòu)質(zhì)量的意見與此也是很相關(guān)的。事實(shí)上，在過去的10年中發(fā)生了一些需要用鋼結(jié)構(gòu)方案解決問題的大事件，例如里斯本國(guó)際展覽（EXPO98）和2004年的歐洲運(yùn)動(dòng)會(huì)，其中，里斯本國(guó)際展覽（EXPO98）的休息亭和特殊結(jié)構(gòu)體現(xiàn)了鋼結(jié)構(gòu)的美感，2004年的歐洲運(yùn)動(dòng)會(huì)有10個(gè)大型足球館使用了有趣的鋼結(jié)構(gòu)屋蓋來建造或改造。因此葡萄牙公眾看到了鋼結(jié)構(gòu)成功的例子并且變得很喜歡這種結(jié)構(gòu)形式。</p><

29、><p>　　The state of the norms for steel structures reflected this decline and Portugal lived with an outdated code until the 1980s. More precisely, a vicious circle of reasons contributed towards a reduction in

30、 the use of structural steel, amongst which was the lack of research and teaching on the subject at universities.</p><p>　　The situation was very different in the field of concrete, where the National Labora

31、tory for Civil Engineering (LNEC) was one of the world’s leading institutions and Portugal was an active participant in the CEB and in the writing of the concrete Model Codes. Portugal being located in an earthquake risk

33、 few years before the 1974 democratic revolution a profound reform of the higher education system took place, namely in Civil Engineering. A large programme of training new researchers in fields not sufficiently covered

44、 he looked for new problems from industry requiring research and design recommendations, have always influenced me in the way I conducted my career.</p><p>　　To maintain contacts, his invitation to join the

45、editorial board of the Journal he founded and to participate as a corresponding member in the group for the Eurocodes he chaired were useful. Later, he supervised João Bento,a close collaborator who, after an M.Sc.

46、thesis in composite construction came to study at Imperial College with Patrick Dowling. Although João Bento worked at the Expert Systems Laboratory, a new interest of Patrick Dowling, this has strengthened his cont

47、acts with IST.</p><p>　　2.Teaching and research</p><p>　　Once back at IST in 1979, teaching steel structures at the undergraduate level was a goal that I could not immediately realise: a semeste

48、r on Steel and Composite Structures was only introduced in 1989. First an optional subject, after 1996 it became compulsory for all the students choosing the Structures profile. </p><p>　　However, the M.Sc.

49、course in Structures, created at IST in 1981, was the vehicle for the education and training of civil engineers in steel construction. Advanced topics such as non-linear behaviour of structures, stability, steel properti

50、es and technology, together with composite structures (following the ECCS Manual) were included in the syllabus. At the same time, short post-graduate courses for the updating of designers were also successfully introduc

51、ed. </p><p>　　But for the use of steel to expand in Portugal it was necessary to develop research into the seismic behaviour of steel structures and in composite construction. M.Sc. and Ph.D. theses on these

52、 topics were promoted. For the seismic aspects cooperation with the Politecnico di Milano was established. Gradually a “steel community” developed, trained in Portugal and abroad.</p><p>　　3.cmm — Portuguese

53、 association for steel and composite construction</p><p>　　The first attempt to create a Portuguese association that could be a member of ECCS dates from 1981. The advice and help of Patrick Dowling was requ

54、ested and given. He came to Lisbon to lecture in the new M.Sc. course and on the advantages of being a member of ECCS, and thus accompany the current development of new design rules. The more relevant institutions were c

55、ontacted to join the association but the attempt failed, surprisingly due to the reservations voiced by the Siderurgia Nacional. </p><p>　　Another unsuccessful attempt was made in 1992, and only in 1997 did

56、we manage to create an organisation named cmm — Associação Portuguesa de Construção Metálica e Mista. It was planned to occur at the closing of the first National Meeting on the subject, organise

57、d in Oporto with the help of the new young professors of Steel Structures. I had the pleasure of inviting Patrick Dowling to be a guest speaker and witness the fulfilment of one of my early objectives.</p><p&g

58、t;　　I presided over this association until April 2005. During these years cmm has grown to over 240 members including the main manufacturers, constructors, designers and researchers interested in the promotion of steel.

59、It is a member of ECCS, as was always intended, and every two years organises national congresses , which are the most important events in the field. The 3rd Eurosteel, held in Coimbra in 2002, was also organised by

60、 cmm. Another objective of cmm has been the establishment of research</p><p>　　The new president of cmm, Luís Simões da Silva, is Professor at the Department of Civil Engineering in Coimbra. He is

61、one of the most distinguished of the younger steel specialists in Europe and also has a Ph.D. from Imperial College. I expect that under his leadership cmm will enter a new dynamic phase, especially in the support of uni
