高性能鋼材應用於建築結構之研究

近年來美、日等國均積極投入高性能鋼材的研發，並已實際應用於橋梁及高層建築工程及耐震、防火等特性之上。除了結構強度與承載能力的考量外，建築結構的安全如構材的變位與建築物的側向位移等服務功能亦爲研發的考量，而橋梁結構則以疲勞與斷裂要求爲重要的設計訴求。由於高性能鋼材具有穩定的材料強度，良好的銲接性能，較大的延展性與相對韌性特性，及良好的抗蝕性，皆爲使得高性能鋼材研究在近年來得以大力發展的主要因素。本研究之主要目標即在於探討高性能鋼材應用於國內建築與橋梁結構之可行性及經濟性，藉由蒐集及分析國內外高性能鋼材研究現況及相關之應用實例，以研析相關課題、對策與研發方向重點。

Recently, high performance steels have been internationally applied to constructions of bridges and buildings with their aseismic and fireproof properties. In addition to considerations of strength demanding, the serviceability and constructability are two other important issues to be taken into account. Based on experiences obtained in Japan and US, high performance steels provide much better alternatives than most other building materials. Thus related researches regarding building technology and material development are hot topics. It is intended in this research to investigate the feasibility of applying high performance steels to domestic buildings and bridges. This study was carried out through collecting and analyzing information of related researches and current practices. Based on both foreign and domestic data, this paper draws certain potential topic, suggests corresponding strategies, and finally proposes developing priorities.
