Thanks sticksandtriangles, I'll give this a go and see how it turns out. For anyone interested or having the same issue, see CSI's response regarding user wind loads onto semi-rigid diaphragms below:
User loads are not recommended to be used with semi-rigid diaphragms since the program applies...
Hi Eng Tips Community,
I am currently in the process of designing the lateral stability system of a 30 storey concrete apartment building. The main lateral stability element is a concrete core box with a few internal walls. Currently the diaphragms are all modelled as semi-rigid as there are...
Further to this, do you believe that precast panel dowels must comply with the minimum reinforcement requirements of Clause 14.6.7? My initial thinking was that As,dowels must be at least greater than As,wall as per Clause 11.7.5. However upon further inspection, the Clause seems to call up...
Hi All,
I am currently designing a multi-story residential building with a precast core box acting as the main lateral stability element with a ductility of u=2. Looking at Clause 14.6.7 in AS3600-2018, vertical and horizontal reinforcement must be provided in both faces of the wall and must be...
Hi QSIIN, do you mean that if we do not receive any tension in the core wall with a μ of 2, we should instead assume non ductile behaviour with a μ of 1 even if the walls go into tension in that situation?
Hi Gishin, thank you for your response. What is the justification behind single leg ties with hooks on both ends being compliant with 14.5.4? It's still unclear as the code references both closed ties and closed fitments within that clause.
I believe Winston's case is similar to the first image...
Hi all,
I feel like we are leaning towards using open ligs rather than fully closed ligs. Given the ambiguity of the new code, can we even justify using open ligs? Is there a process we can go through to quickly clarify these requirements?
Given that this is a new requirement, I've not...
I've read through the draft for the 2nd Amendment of AS3600-2018 but could not find any clarification on which 'closed tie' the code committee is trying to specify. Even in Clause 14.6.2.3 they specify closed ligatures but in Figure 14.6.2.3 they show what is defined as closed ties.
Is the...
