摘要 摘要 關鍵詞：鋼結構、設計規範、本土化參數、新式鋼材 我國現今的「鋼構造建築物鋼結構設計技術規範」為內政部營建署於民國 96 年 7 月 1 日頒佈實施，歷經 15 餘年之產業與專業技術進步，國內鋼結構工程技術有相當程 度之變化與增進，包括材料規定、製造、吊裝與檢驗等方式均有改變。綜合國內、外新 近鋼結構技術與規範之修訂方向與內容、及鋼結構施工技術發展與研究成果，針對我國 未來鋼結構建築物設計之需要，已初步研擬新版的「鋼結構設計規範」草案。新版規範 (草案)是依據美國鋼結構協會 AISC 規範架構與相關研究成果編定，然規範中有不少規 定之背景條件與考量因素仍和我國情況不同，為使新版規範能符合我國情況，本研究針 對我國鋼結構環境，研究符合我國鋼結構工程需要之內容。美國 AISC 是以活載重為靜 載重的 3 倍來考慮相關載重組合，而台灣的載重大小反而是靜載重大於活載重大，此項 載重情況會影響「容許應力設計法 ASD」與「極限強度設計法 LRFD」之架構，新版規 範是將 ASD 與 LRFD 兩設計法合併在一起，以 LRFD 法為主來訂定規範內容，而 ASD 則以參數方式修改後使用，為使 ASD 在台灣能合理使用與推動，符合國內工程特性 ASD 設計法之安全係數可適度調整。 對於鋼板之材料規定，我國(CNS)大都參照日本規範，雖然目前新版鋼結構設計規 範草案有參考兩者的差別，並依我國情況做調整，但針對較特殊的耐震結構物與特殊之 施工方式，本研究完成新式鋼板材料因應我國本土耐震需要之最新材質定義與規格，可 提供國內設計單位均一規格化之運用依據。台灣地區活載重大小對「容許應力設計法 ASD」與「極限強度設計法 LRFD」架構之影響，因應新版規範 ASD 與 LRFD 兩設計法 合併使用之差異探討，LRFD 法為主之架構下，ASD 設計法可取更加經濟之參數，依本 研究初步探討，ASD 安全係數可酌予放寬約 10%。 本研究相關成果，歸納出下述的主要結論： 1. 本次鋼結構設計技術規範修訂研擬研究，將現行規範的容許應力設計法與極 限設計法兩冊合併為一冊。將容許強度設計法取代現行規範的容許應力設計 法，並以構材極限強度與機率式載重準則結合的 LRFD 設計法為修訂基準， 使容許強度設計法與 LRFD 設計法具相同安全等級的設計結果。 2. 為提升鋼結構建築的耐震設計有效性，本修訂版本於第十四章耐震設計中導 入材料的預期實際強度概念，做為構材或元件的強度容量設計基準，以期確保 VII

Abstract Abstract Keywords: steel structure, design specification, local parameters, state-of-art steel materials In Taiwan area, current "Design Specification for Design and Construction of Steel Structure Buildings" was promulgated and implemented by the Ministry of The Interior on July 1, 1996. After more than 15 years of industrial and professional technological progress, domestic steel structure engineering technology has undergone considerable changes and enhancements, including changes in material regulations, manufacturing, hoisting and inspection methods. Combining the revision direction and content of recent domestic and foreign steel structure technologies and specifications, as well as the development and research results of steel structure construction technology, in response to the needs of future steel structure building design in Taiwan, a new version of the "Steel Structure Design Specification" draft has been preliminarily developed. The new version of the code (draft) is based on the AISC code structure and related research results compiled by the American Institute of Steel Construction. However, the background conditions and considerations of many provisions in the code are still different from the situation in Taiwan steel industry. In order to make the new version of the code conform to the situation in Taiwan, the research is aimed at the steel structure environment conformation for Taiwan area, and the research meets the needs of steel structure engineering. AISC in the United States considers the relevant load combination based on the live load as three times the static load, while the load in Taiwan is that the static load is greater than the live load. This loading condition will affect the framework of Allowable Stress Design method(ASD) and Load and resistance factor design method(LRFD). The new version of the specification combines ASD and LRFD design methods together, the LRFD method is mainly used to formulate the specification content, while the ASD is used after modification in the form of parameters. In order to make the ASD can be used and promoted reasonably in Taiwan, the safety factor of the ASD design method that conforms to the domestic engineering characteristics can be adjusted appropriately. For steel plate material regulations, Taiwan’s code (CNS) mostly refers to Japanese standards, although the current draft of the new steel structure design code refers to the difference between the two, adjustment according to the situation in Taiwan should be done for further application. However, for more special earthquake-resistant structures and special construction methods, this research completes the latest material definition and specifications of new steel plate materials to meet local earthquake- resistant needs, which can provide a basis for uniform and standardized use by domestic design facilities. The impact of the live load in Taiwan on the frameworks of Allowable Stress Design method(ASD) and Load and resistance factor design method(LRFD), in response to the differences in the combined use of the two design methods ASD and LRFD in the new version of the code, under the framework of the LRFD method, ASD design The method can adopt more economical parameters. According to the preliminary discussion of this study, the ASD safety factor can be relaxed by about 10%. IX

新版鋼結構設計技術規範中 因應我國載重與工程特性之相關參數研究 The main conclusions of this research can be summarized as follows: 1. This study on the revision of the steel structure design technical specification combines the two volumes of the allowable stress design method and the limit design method of the current code into one volume. 2. In order to improve the effectiveness of the seismic design of steel structures, this revised version introduces the concept of expected actual strength of materials in Chapter 14 of seismic design, which serves as the basis for the design of the strength capacity of members or elements, as well as ensure the actual strength of the building structure. The seismic behavior is as consistent as possible with the design assumptions. 3. The revision draft on this research adds domestic engineering practice requirements, or seismic systems with high-efficiency seismic performance, including: seismic structural systems such as cantilever columns, buckled braces, and steel plate shear walls, and related seismic design regulations. In total, the various structural systems that can be used for seismic design in this draft code are stipulated in Chapter 14 14.5~14.14 of the draft code, including 14.5 Ordinary Moment- resistant Frame, 14.6 Partial Moment-resistant Frame, 14.7 Special Moment-resistant Frame, 14.8 General Cantilever Column System 14.9 Special Cantilever Column System, 14.10 Ordinary Concentric Braced Frame, 14.11 Special Concentric Braced Frame, 14.12 Eccentric Braced Frame, 14.13 Buckling Restrained Braced System Frame, 14.14 Special Steel Plate Shear Wall. 4. This revision of the steel structure design technical specification (draft) has greatly added the combined regulations for hollow structural section (HSS) steel pipes. This part will help the domestic development of local facilities design and construction technology for offshore wind power support structures. 5.
