This paper aims to investigate structural health monitoring oriented finite element modeling for the tower of long-span bridges.

首先采用不同的方法分别建立了大跨桥梁索塔的精细有限元模型和简化模型，运用环境振动实测结果对简化有限元模型进行了修正，并和精细模型计算结果相比较；研究结果表明：严格按照设计图纸建立的精细有限元模型计算得到的动力特性与索塔现场环境振动实测值之间的误差较小，而未经修正的简化模型误差较大，由此说明：大跨桥梁在有限元建模时应尽可能详细地反映结构的几何与材料特性，在此前提下，对于设计资料全面的桥梁结构，建立有限元模型时就只需要修正那些无法用数学和物理方法模拟的不确定因素。

Considering no construction analysis oriented software for long-span space structures exists in the domestic engineering software market in China, a constructionmodule is developed upon the platform of MSTCAD, a famous domestic software for space grid structures design. This will not only enhance the software functions, but also meets the growing domestic demand for construction analysis software.

最后，针对目前国内大跨度空间结构施工分析软件缺乏的现状，在MSTCAD软件平台上增加施工功能的吊装模块，在模块中实现吊装的目标函数满意度选择起吊高度功能和最小应变能法选择吊点布局的功能，并且通过各类吊装参数的预输入给予用户方便快捷的选择，使得MSTCAD软件逐步完善成为国内领先的设计及施工分析软件。

The CO-OCS algorithm chooses the right regular vector of the user channel as the beamforming vector and the row span as an interference space from the left regular vectors of the interference channels. A suitable user lying in the orthogonal complement space of the interference space is scheduled to be free of suffering inter-cell interference and aggravating the interference in neighboring cells.

分布式干扰协调算法根据用户反馈的信道信息，以用户信道右奇异值向量发送波束成形，以干扰信道左奇异值向量张成干扰空间，按照最大化系统容量准则调度干扰空间的正交补空间中的用户，在躲避小区间干扰的同时不增加对邻小区的干扰。

The split between the two groups can hardly be papered over.
