Applying finite element method,the elastic ultimate load and plastic or stability ultimate load corresponding to the allowable stress method and ultimate state method of concrete filled steel tube(CFST) columns with initial stress under axial loads are calculated and analyzed. 应用有限元计算方法,对有...
This limits the use of high strength carbon steel, such as steel grade X80 or higher. The yielding check implicitly covers other failure modes as well. To extend the material grade beyond the current limit, explicit checks for other failure modes may be necessary; see Chapter 4. DNV-OS-...
The yield strength of CFT columns is determined by 2/3 of compressive force of concrete in most cases. And the yield strength of CFT columns is smaller than the allowable strength. However, as an important index representing the damage state of CFT column, the stress state of steel tube ...

The failure stress was calculated using the failure pressure and the design margin was defined as the ratio of the failure stress to the allowable compressive stress. The tentative lower limit for the design margin was set to be 2. 0 and at least 1. 5. For A5083-O and 9% Ni steel, ...
Examples of steel plated structure include ships, offshore installations, bunkers, box girder bridges and box girder cranes [1], [2]. In the past, steel plated structures have typically been designed using the allowable working stress based design method (AWSDM). In the AWSDM, the structural...
Maximum allowable stress developed at the minimum cross-section area of the bar. So it is the ratio of applied load to the minimum cross-section area. Answer and Explanation:1 Given data, All the dimensions are shown in the given...
(1988) [29] is used to consider the enhancement of compressive strength and ductility of concrete in the region confined by shear rebars in the cross section of RC columns. The model for the main rebar is based on Steel02 material, where strain hardening can be applied. Figure 2. ...
Normal stress can be defined as, when a body is subjected to an axial force than its shape and size will be changed. Due to this axial force that has been applied on the body, the body will expand or compress. This condition of stress will ...
