对于较大的应力变化范围和较大的荷载变化幅度的作用力,必须按照 EN 1992-1-1 进行疲劳验算。 在这种情况下,混凝土和钢筋的设计是分开进行的。 有两种计算方法可供选择。
本文以钢纤维混凝土板为例,为您介绍使用不同的积分方法和不同的积分点数对计算结果的影响。
为了在 RFEM 6 和“混凝土设计”模块中正确设计梁或 T 形梁,确定带肋杆件的“翼缘宽度”非常重要。 本文介绍了两跨梁的输入选项以及根据 EN 1992-1-1 计算翼缘尺寸。
如果计算规则的结构,输入通常并不复杂,但非常耗时。 自动化输入可以节省宝贵的时间。 本例中的任务是将房屋的楼层视为独立的施工阶段。 必须使用 C# 程序输入,这样用户就不必手动输入各个楼层的元素。
在 RFEM 6 的混凝土设计模块中,可以根据简化表格法(EN 1992-1-2,章节 5.4.2,以及表 5.8 和 5.9)对钢筋混凝土墙和板进行抗火设计。
在“混凝土设计”模块中,您可以定义竖直抗冲切配筋。 在进行冲切设计时需要考虑这一点。
在混凝土设计模块中,您可以按照欧洲规范 EN 1992-1-2 对柱子(章节 5.3.2)和梁(章节 5.6)进行简化防火设计。
Für den vereinfachten Brandschutznachweis stehen Ihnen folgende Nachweise zur Verfügung:
- Stützen : Mindestquerschnittsabmessungen für Rechteck- oder Kreisquerschnitte nach Tabelle 5.2a sowie die Gleichung 5.7 für die Berechnung der Branddauer
- Balken : Mindestmaße und -achsabstände nach den Tabellen 5.5 und 5.6
Die Schnittgrößenermittlung für den Brandschutznachweis kann nach zwei Verfahren ermittelt werden.
- 1 Hier fließen die Schnittgrößen der außergewöhnlichen Bemessungssituation direkt in die Bemessung ein.
- 2 Hier werden mittels des Eta,fi (ηfi) Faktors die Schnittgrößen der Kaltbemessung abgemindert und werden dann in der Heißbemessung verwendet.
Weiterhin ist es möglich sich den Achsabstand nach Gl. 5.5 ermitteln zu lassen.
