Zum Ermüdungsnachweis von druckschwellbeanspruchtem Beton

Oneschkow Nadja; Lohaus Ludger

摘要

Abstract xml:lang="de">Für ermüdungsbelastete Bauwerke, insbesondere aus hochfesten Betonen, wird der Ermüdungsnachweis immer h?ufiger ma?gebend für die Bemessung. Gleichzeitig existieren neuere Untersuchungsergebnisse, die zeigen, dass eine Weiterentwicklung des Ermüdungsnachweises sinnvoll und erforderlich ist. Das Sicherheitskonzept des Ermüdungsnachweises ist angelehnt an das Konzept der statischen Bemessung. Hieraus ergeben sich Besonderheiten und Herausforderungen bei der Weiterentwicklung des Nachweiskonzepts. Im Teil 1 dieses Artikels [1] wurde ein überblick über die Struktur des Ermüdungsnachweises gegeben und die enthaltenen Beiwerte erl?utert. In diesem Artikel werden die W?hlerkurven mit aktuellen Versuchsergebnissen verglichen und der Effekt des Bemessungswerts der Druckfestigkeit von Beton bei Ermüdungsbeanspruchung herausgearbeitet und vor dem Hintergrund sicherheitstheoretischer überlegungen diskutiert. Das Potenzial für Weiterentwicklungen wird hierauf aufbauend aufgezeigt. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><abstract xmlns =“http://www.wileey.com/namespaces/wiley”type =“main”xml：lang =“de”> <标题类型=“main”>抽象</ title> XML：Lang =“de”>对于疲劳相关的结构，特别是从高强度强调，疲劳证据变得越来越流行。与此同时，近期的考试结果表明，疲劳证明的进一步发展是有意义的，有必要的。疲劳检测的安全概念基于静态设计的概念。这导致诸如证据概念的进一步发展中的特殊性和挑战。在本文[1]的第1部分中，给出了疲劳证明结构的概述，并包含包含的值。在本文中，比较了具有当前测试结果的赌注曲线，并且混凝土耐压性耐压设计值与疲劳应力的效果效果，并讨论了安全理论考虑的背景。在这个阶段建立了进一步发展的潜力。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" > 著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-14835/'>《Beton- und Stahlbetonbau 》</a> <b style="margin: 0 2px;">|</b><span>2017年第9期</span><b style="margin: 0 2px;">|</b> <span>共12页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Oneschkow Nadja&option=202" target="_blank" rel="nofollow">Oneschkow Nadja;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Lohaus Ludger&option=202" target="_blank" rel="nofollow">Lohaus Ludger;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Institut für BaustoffeLeibniz Universit?t HannoverAppelstra?e 9a 30167 Hannover;</p> <p>Institut für BaustoffeLeibniz Universit?t HannoverAppelstra?e 9a 30167 Hannover;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li> <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>other</span> </li> <li> <span class="lefttit">中图分类</span> <span> <a href="https://www.zhangqiaokeyan.com/clc/240.html" title="建筑科学">建筑科学 ;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ermüdung&option=203" rel="nofollow">Ermüdung;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Bemessung&option=203" rel="nofollow">Bemessung;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Sicherheit&option=203" rel="nofollow">Sicherheit;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Nachweiskonzept&option=203" rel="nofollow">Nachweiskonzept;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=UHPC&option=203" rel="nofollow">UHPC;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Baustoffe&option=203" rel="nofollow">Baustoffe;</a> </p> <div class="translation"> 机译：疲劳;尺寸;安全;检测概念;UHPC;建筑材料;
