框架梁端部开孔这么大,怎么没有补强?还未完工的原因?

This is cellular beam (蜂窝梁)which is very popular in Europeean countries because they do not need consider earthquake resistance.  
But in earthquake regions like China, it is not recommended.

应力集中的问题本身与洞口大小无关,主要是在洞口的四周存在;
这样,是否考虑地震设防好像也不是主要问题。
楼主能否讲讲,图上洞口很大,那么,上下翼缘如何考虑?

在梁端开这么大的洞没有见过
好像有些不可思议。
希望楼主给小弟详细介绍一下好么
谢谢

我记得蜂窝梁的第一个孔的孔边到支座边缘的距离不得少于250mm,看这个图我感觉好象不太够。国外的蜂窝梁也需要满足这个要求吧?
