[软件]Mander Confined Strength Ratio Calculator[Mander混凝土本构约束强化系数]

  • 引言(Introduction):

上一篇博文Mander Confined Concrete Model 资料整理总结了Mander模型参数的计算方法,其中该模型十分关键的一个参数为约束混凝土的峰值强度fcc’。关于fcc’的确定,Mander模型原文(Ref. 1)给出的方法为:首先确定两个方向的约束系数,然后通过查图得到约束强度系数(Confined Strength Ratio),进而得到fcc’(博文Mander Confined Concrete Model – Confined Strength Ratio [Mander混凝土本构约束强化系数]》也提到),不方便使用。

原文给出的约束强度系数(Confined Strength Ratio – fcc’/fco’)图:

Confined Strength Ratio - Mander

为此,编制小程序计算Mander模型的约束强度系数,程序如下图所示。

  • 程序功能(Program Features

程序通过输入两个方向的有效约束系数,计算Mander混凝土模型的约束强度系数,省去查图的过程,方便平时做数值模拟。

This program is for calculation of the Confined Strength Ratio of Mander Confined Concrete Model proposed by Mander  in 1988. 

  • 实例(Examples):

(1)柱子非约束混凝土强度fco’ = 30Mpa,两个方向的约束应力为flx’ = 2.7Mpafly’ = 5.1Mpa,求约束混凝土的峰值强度fcc’(Consider a column with an unconfined strength of fco’=30Mpa and confinning stresses in two direction are flx’= 2.7Mpa and fly’ = 5.1Mpa respectively,calculate the compressive strength  fcc’ of the confined concrete)

约束系数计算( Confinning stresse ratio ):

 flx’/fco’ = 2.7/30 = 0.09;

 fly’/fco’ = 5.1/30 = 0.17;

软件计算过程(Get Confined Strength Ratio by Software):

输入两个方向的约束应力系数,点击“Calculate”按钮。(Input the confinning stresse ratio in two direction and press the ‘Calculate‘ button.

ManderConfinedStrengthRatioCalculator-Example1

约束混凝土强度系数(Confined Strength Ratio):

 fcc/fco’ = 1.6515760

约束混凝土强度(compressive strength  fcc’ ):

fcc‘ = 1.651576 × 30 = 49.55 Mpa

(2)柱子非约束混凝土强度fco’ = 30Mpa,两个方向的约束应力为flx‘ = 3.0Mpafly’ = 8.4Mpa,求约束混凝土的峰值强度fcc’(Consider a column with an unconfined strength of fco’=30Mpa and confinning stresses in two direction are flx’= 3.0Mpa and fly’ = 8.4Mpa respectively,calculate the compressive strength  fcc’ of the confined concrete)

约束系数计算( Confinning stresse ratio ):

 flx’/fco’ = 3.0/30 = 0.1;

 fly’/fco’ = 8.4/30 = 0.28;

软件计算过程(Get Confined Strength Ratio by Software):

输入两个方向的约束系数,点击“Calculate”按钮。(Input the confinning stresse ratio in two direction and press the ‘Calculate‘ button.)

ManderConfinedStrengthRatioCalculator-Example2

约束混凝土强度系数(Confined Strength Ratio):

 fcc/fco’ = 1.7971448

约束混凝土强度(compressive strength  fcc’ ):

fcc= 1.7971448 × 30 = 53.91 Mpa
