Is there any software that can Model a masonry vault or arch as shown in the picture attached ?
And if anyone can help me on how to check the stability of such element ? (any reference, books or articles are very much appreciated)
When I Model a Shear Wall in Etabs and at both end of the shear wall I model a Column, After Running The Analysis and see the design of the Columns I notice that always I have a High Percentage of rebar needed for the columns, is it normal that the columns play the role here as boundary elements...
Hi, I modeled a 44 story building in ETABS and I want to design its foundation on SAFE, the foundation consists of MAT on Piles, I must say that all my supporting elements consist of shear walls.
The mat foundation (concrete f'c 35 MPa) 2 m thick and having punching shear reinforcement around...
I have a mat foundation on a pile foundation (150 piles with a mat foundation 23*36 with a pile of 80 cm diameter and a length of 30 m) I checked the mat foundation in SAFE and I checked the piles for axial load, but I need to check the piles for seismic loads (lateral loads), How to model the...
I have a raft foundation and a 44 story building with only shear walls as vertical elements and I am using ACI318M-11, I checked the punching shear of these shear walls as the following picture shows, I took Pu (the ultimate vertical load on the shear wall) to find the effective thickness d. (if...
thread507-312949 In this thread there was a talk about precompression maximum value, can anyone explain to me what is the difference between precompression and compression in the upper fiber that is checked in the transfer stage ? (ACI 318/318R-8 clause 18.4.1 states that at transfer we mus...
Hi, I have a post-tension slab I want to draw it in autocad but i don't know how many plans to present and how each plan layout, can anyone present any sample autocad or pdf showing layout of slabs presented by a company or office ?
For a PT slab with tendon/distributed layout what is the best profile parabola or reverse parabola for each direction ? and what is the difference between these two profiles and their impact on the stresses ?
How the tendon profile is calculated for banded-distributed disposition? In the following figure why is the tendons profile one in the top fiber and the second in the bottom fiber? If the location is at the middle of the slab why do we place them opposite to each other doesn't that cancel the...
I am asking this question because in the field I saw that the jacking is the same but elongation for each tendon, but doesn't each tendon needs it's own jacking force because in the design each tendon is subjected to different moment and load ?
