非結構牆對建築物振動週期及地震力之影響

為了解決Nicee的問題，作者曾清學 這樣論述：

中文摘要目前一般鋼筋混凝土造建築物在進行結構設計時，並不會將非結構RC牆一併納入進行分析，同時採用法規經驗公式T=0.07hn0.75與動力分析之週期比較，因此高估建築物之振動週期，而低估建築物的設計地震力。由於強烈地震之振動時間很短，僅數十秒，雖然非結構牆會損壞，但對整體結構勁度的影響是局部且有限。有關之文獻研究亦顯示鋼筋混凝土建築物微震所測得之建築物週期，均比規範所建議之經驗公式低。本研究的目的在探討建築物之窗台、外牆及電梯牆等鋼筋混凝土非結構牆對建築物基本振動週期及地震力之影響。研究方法是利用SAP2000程式分析各種不同樓高僅有梁柱結構之純構架及含有非結構牆之構架基本振動週期，進而依

耐震設計規範計算花蓮市近斷層2公里以內之最小設計水平總橫力係數。結構分析及設計建立5層、10層、15層、20層、25層、30層等6種不同樓層規則鋼筋混凝土建築物模型，其中每種樓層建築物又分為(1)梁柱結構系統(SMRF)；(2)梁柱結構+加窗台及電梯等非結構牆(SMRF-P-E)；(3)梁柱結構+加外牆及電梯等非結構牆(SMRF-W-E)；(4)梁柱結構+加外牆及電梯等非結構牆+剪力牆(SMRF-W-E-SW)。總共分析24棟住宅建築，探討非結構牆對建築物基本振動週期及地震力之影響。研究顯示:考慮非結構牆後，由於非結構牆增加結構之勁度，降低結構之週期，因此增加建築物設計地震力。建議一般鋼筋混凝

土造建築物在進行結構設計時，如果不將非結構RC牆一併納入進行分析，建議應採用法規經驗公式T=0.05hn0.75與動力分析之週期比較。

應用非線性側推分析於地下自來水管線受斷層錯動之研究

為了解決Nicee的問題，作者陳振豪 這樣論述：

地震為台灣常見天然災害之一，當地震發生時，除了地表上之結構如房屋或橋梁會受到損壞之外，地下結構如自來水管線或是結構物基礎亦可能受到損壞，其中由於水為民眾每天所需之物資，因此當地下自來水管線因地震產生損壞而無法提供正常服務功能，則勢必產生民生與衛生問題，更可能因此產生二次災害如火災與瘟疫，故自來水管線因地震所引起之損壞不可不視。當地震發生時，地下自來水管線可能因地層錯動或液化而發生損壞，其中以地層錯動所引起之破壞最為嚴苛，故許多研究皆是探討管線受地層錯動下之行為。本研究旨在利用側推分析來探討連續管受地層錯動之行為，一般而言，當連續管受到地層錯動時，管體可能因承受過大之彎矩而發生局部挫屈，因此如

欲以側推分析來探討連續管受錯動行為，則需有合適的非線性鉸來模擬管體行為，因此本文便針對地下自來水管線建立一考慮局部挫屈之彎矩非線性鉸；此外本文並建立一軸力非線性鉸，得到管構件之非線性鉸後，工程師可用於側推分析，並對連續管受地層錯動之行為有一初步分析，其中由於國內輸配水管線常使用之管材為延性鑄鐵管，因此本文之研究管材選擇了延性鑄鐵管。本研究之案例分析探討了直徑400mm連續管受平移斷層錯動之行為，其中連續管受平移斷層之行為又可分為拉力加撓曲控制與壓力加撓曲控制，在拉力與撓曲控制的案例分析之結果發現，在二階效應下，管體最大彎矩會因拉力所產生之二階彎矩而變小，因此不易發生局部挫屈，其中對於拉力破壞之

案例而言，分析所得到之管線容許斷層錯動量非常接近Newmark與Hall之理論解，但對於撓曲破壞之案例而言，Newmark與Hall之理論解則會高估管線容許斷層錯動量；在壓力與撓曲控制的案例分析結果發現，在二階效應下，管體最大彎矩會因壓力所產生之二階彎矩而變大，因此更容易發生局部挫屈，且其容許斷層錯動量與拉力加撓曲控制下的容許錯動量相比會較小。
