    Recommendations for Literature on Shear Wall Analysis and Design

    Hi there, I am interested in understanding shear wall analysis and design in detail. For design purposes, I'll prefer guidelines which address CSA A23.3 (Capacity Based Design) clauses when designing shear walls. It'd be great if someone can recommend some good books / Handbooks / articles on...

    Exploring Damped Outriggers for Seismic Response Reduction: Seeking Resources and Insights

    Hi there, I'm an M.Eng student focusing on Nonlinear Time History Analysis (NLTHA) for tall RC buildings. My capstone project revolves around implementing damped outriggers to minimize seismic forces' impact in seismic prone region. Currently, I'm seeking resources to understand the...

    Struggling with Basic Masonry Design Problem

    Thanks everyone for your input. I wasn't expecting this much help but you guys went above and beyond to assist me in this and I really appreciate it. @LittleInch Thing is that client isn't interested in any proposal and just wants to make sure that whether the proposed layout will work out or...

    Struggling with Basic Masonry Design Problem

    Thanks a lot for responding. Moreover, apologies for this poorly written thread. I agree that problem statement could have been explained a lot better. It's a fence (boundary) wall and besides self-weight of the wall, wind and seismic forces are to be considered. The fence wall is located in...

    Struggling with Basic Masonry Design Problem

    Hi everyone, I'm in a bit of mess currently, due to Masonry Design of Hollow blocks - fully grouted. Thing is I'll pursuing master's from abroad starting this fall and already have informed my boss that I'll be leaving office at the end of this month. While I have extensive experience in...

    Understanding Seismic base shear distribution at podium level

    Hi there, I have this habit of going through ETABS models of buildings being designed in our office to understand the behavior of structures. So I was just going through this multi-tower model with initial framing and parameters as per instructions and submitted it to my senior who'll carry out...

    Torsional mode as fundamental mode in Multi-tower Building

    Thanks @Kootk for the recommendations. Luckily, I have "Tall Building Structures" by Bryan Stafford Smith, and "Dynamics of Structures" by Chopra. The first one (Tall Building Structures) was recommended by my boss, and since he had its first edition in his personal library, he gave this book...

    Torsional mode as fundamental mode in Multi-tower Building

    @Tomfh I was trying to narrow down the eccentricity between the centre of mass and Centre of Rigidity, as @Chris3eb mentioned in his comment too. It seems like I wasn't looking at the big picture and I am glad that I asked you guys for guidance. Thanks! @Kootk Thanks a lot for helping me out. I...

    Torsional mode as fundamental mode in Multi-tower Building

    @KootK Let me know what exactly you meant by "extent of coupling". A bit embarrassed though because if I was in your place, I'd have been surprised too realizing that one doesn't know simple terminology. BSc. Graduate

    Torsional mode as fundamental mode in Multi-tower Building

    Hi there, It's going to be a long post but please bear with me. I am currently working on a multi-tower building with a common podium. For high-rise buildings, I am normally assigned the task of creating a finite element model with gravity loads properly applied so as to assist my senior, who...

    Struggling in understanding application of Stiffness modifiers for different building systems

    Hi there, I am currently assigned to make the general layout of High rise building in ETABS, and once my senior reviews basic framing, he'll take over the model and carry on with the setting up Dynamic (Response Spectrum) parameters, etc and then on to design process. Thing is that I am very...

    Having problem in modeling stairs in Revit

    Hi there, I have recently started learning Revit, and currently, I am stuck on this issue of modeling stairs. I am working on a Revit model in which I am supposed to provide a structural layout of the building only(Formwork for concrete). Due to this, I am not considering structural finishes in...

    Exporting REVIT model to ETABS

    Hi there, I needed some help with converting Revit model to Etabs for structural analysis. I have CSixrevit installed in Revit. When I import this model in ETABS, only columns and grids are shown. Anything else is not imported. Secondly, I tried importing IFC file of Revit model in Etabs, and...

    Excessive reinforcement in columns

    @SWComposites Thing is, when columns are designed based on ETABS output (Moment and Axial force) manually, I don't have to provide so much reinforcement (As =29 in^2 as reported by ETABS is way too much for even this load). I am interested in finding out why ETABS output, especially at...

    Excessive reinforcement in columns

    Hi there, I am a junior engineer, currently working on textile mill project and facing an issue, which I haven't been able to resolve for past 3-4 days. Story heights for textile mill have been shown in images. On Gridlines 17,18,19 and 20, an AC station will be placed and its subsequent loads...

    Struggling in understanding structural drawings

    Thanks a lot for these recommendations. I looked into "Manual for detailing Reinforced Concrete Structures to EC2" and found it very useful. Your recommendations is exactly what I was looking for. I'll try to study these drawings and I am quite hopeful that with time, I'll be able to overcome...

    Struggling in understanding structural drawings

    We do all these projects you just mentioned. Currently, we are working on two high-rise buildings, one having a sky bridge and the other is 20 story building. Before these, I worked on a school building and an embassy. We mostly deal with concrete buildings. All though I have done Bsc, my...
