为了论证网架在设计时应与下部结构进行整体计算的必要性,以三种支撑下(刚铰支座、弹性支座和柱子支撑)的双层正放四角锥矩形网架为研究对象,应用ANSYS对多个网架结构的挠度、压杆、拉杆进行对比研究,得出如下结论:刚铰支座与弹性支座、整体分析网架的杆件动静力分布规律截然不同,必须考虑下部结构刚度对网架杆件受力的影响,不可简单地简化为刚铰支座,否则设计极不安全;以弹性支座网架模型代替整体分析网架模型有一定的可行性,二者在内力分布及大小较相近,但也有不少杆件应力偏差较大。
补充资料:弹性刚度常数
分子式:
CAS号:

性质:又称弹性劲度常数。弹性体在单位应力下发生的应变。是弹性体刚度的一种量度。通常用Cij表示,单位为Pa,由于压电体存在二极压电效应,在电学条件不同时,所测得的弹性刚度常数也不相同。在短路条件下测得的弹性刚度常数,称为短路弹性刚度常数,用表示。在开路条件下测得的弹性刚度常数,称为开路弹性刚度常数,用表示。弹性刚度常数共用10个,即、、、、和、、、和。压电陶瓷是弹性体,可用弹性刚度常数进行评价。弹性刚度常数值愈小,弹性体愈容易形变;其值较大,材料比较刚硬。
