Midascivil荷载组合详解
主要根据公路桥涵设计通用规范(JTGD60-2004)编制。
在结果>荷载组合对话框中选择自动生成”功能。
a.在荷载>
移动荷载分析数据中定义移动荷载时,下面组合中的符号L
用ML代替。
b.反应谱荷载工况的简称为ESPc.在荷载>
移动荷载分析数据中,将人群荷载按移动荷载定义,并在移动荷载工况中将其与其它汽车荷载子荷载工况进行组合时(在移动荷载工况中选择组合”)在定义人群荷载子荷载工
况时,系数应取0.8(根据通用规范4.1.6条第1项)。
为了考虑人群荷载单独作用的情况(系数1.0的情况),需要另外单独定义一个人群荷载移动工况。
d.下面组合中考虑了可
变荷载作用的不同时组合(JTGD60-2004中表4.1.5)e.不考虑汽车荷载的恒荷载+其他可变荷载的组合及组合值系数需用户另外添加(规范无规定)。
f.永久荷载中既有对结构承载能力不利,又有对结构的承载能力有利的永久荷载时,需要用户另外添加组合或修改永久荷载对结构的承载能力
有利组合”中的系数。
g.在荷载组合自动生成对话框中选择
考虑弯桥制动力”时,当汽车制动力与离心力同时由现在荷
载组合中时,制动力荷载的组合系数自动乘以0.7的系数。
h.程序会自动生成各状态组合的包络组合。
i.钢结构的组
合依然沿用旧规范。
j.当有移动荷载作用时,在设计中实际采用的组合会更多(对每个荷载组合都会对弯矩最大时、
剪力最大时、轴力最大时的情况进行验算)。
k.在荷载>静
力荷载工况中定义荷载名称,但没有具体定义荷载值时,荷
载组合的自动生成功能将不包含该荷载工况名称。
1.预应
力混凝土设计荷载组合在荷载组合的混凝土”中定义。
