I graduated from Damascus University, Faculty of Civil Engineering in 2016. I was awarded the MEXT Scholarship from the Japanese government, then started my master's course at Graduate School of Engineering, Tohoku University in Japan. I completed my master course in September 2020. I am currently doing my PhD at Graduate School of Engineering, Tohoku University.
The high in-plane shear strengths of cross-laminated timber (CLT) make it a good candidate for use as shear walls in buildings in areas of high seismicity such as Japan. One important aspect of CLT walls, and one that is presently poorly understood, is the influence of openings on the in-plane shear carrying capacity. The main purpose of this paper...
Improved understanding of ground motion demands of earthquakes and advancement in seismic design has allowed engineers to build structures that will sustain limited damage after an earthquake. This has reduced the number of collapsed structures, but also increased the number of lightly to moderately damaged structures that need to be assessed, in o...
In the last decade, cross laminated timber (CLT) has been receiving increasing attention as a promising construction material for multi-storey structures in areas of high seismicity. In Japan, application of CLT in building construction is still relatively new; however, there is increasing interest in CLT from researchers as well as construction co...
In part 1 and part 2 of this study the experimental program and results of diagonal compression tests of CLT panels with openings were reported. In order to investigate the effect of opening parameters beyond those in the experimental program, a finite element model (FEM) model can be utilized. In this part (part 3) an FEM modelling approach is pre...
Timber products are being increasingly utilized in mid-to high-rise buildings in Japan as it is a sustainable and eco-friendly material. Cross laminated timber (CLT) is one possible candidate for wide use in construction because of its high strength and stiffness characteristics. However, the development of effective seismic connections between tim...
Visualizing the strain distribution throughout tested structural components provide a better understanding of the internal load paths and the final failure mechanism that may not be immediately obvious from visual observation. The Digital Image Correlation (DIC) method allows a strain distribution field of an entire surface of tested components to...
Hello everyone, I am trying to model a CLT panel as shell element using composite layup and do the analysis under static loads. I defined the material as an orthotropic material using engineering constants. However, I am looking for a way to model the failure of the material and get a failure force. I have read about Hill criteria, Tsai-Wu criteria and also Hashin criteria but I couldn't get to way to model the failure.
Can you please give me some explanation or reference on how to define failure criterion for orthotropic material?
any help would be greatly appreciated. Thanks a lot.
I am trying to model a Cross Laminated Timber panel using Abaqus, and I am inserting the elastic behaviour for an orthotropic material. However, I am not sure how to take the plastic behaviour into account.
Dose anyone know how to model an orthotropic material plasticity using Abaqus?
Thank you in advance.
Investigate the influence of openings in CLT shear walls on seismic performance (shear strength and initial stiffness). Additionally, propose an evaluation method for shear strength and stiffness of CLT shear walls with openings.
