As a multi-skilled Engineer adept in various design, analysis, and simulation software, I am highly capable of meeting the complex challenges that your seismic pallet rack stability project entails. With a deep understanding of Finite Element Analysis (FEA), particularly in simulation and structural stability assessments, I assure you that I can deliver reliable results for checking overturning, sliding, or separation between levels. My expertise in AutoCAD, SolidWorks, Revit, Tekla and more enables me to flawlessly simplify 3D geometry without compromising accuracy- thereby optimizing mesh and computational time as you requested. In reference to the rolling simulation component of the racks, I am experienced in dealing with rigid body dynamics - thus modelling the 280kg rolls according to your needs presents no challenges. Similarly, my familiarity with designing single-rigid body simulations will provide an efficient approach throughout all stages of your project. Moreover, my knowledge of geotechnical engineering combined with extensive skills in structural verification and seismic action application via time-history analysis equip me with a solid foundation to handle this task successfully.

Hi there,I have done similar works for pallet rack design including seismic loads. I can share sample of my previous works over chat I'm looking forward to working with you Regards

Hello, I can evaluate you structure on Earth quake, simple gravity, earth quake will be considered in the side and front back accelerations. I am using ansys for evaluation stresses. Feel free to contact me and ask me additional questions.

I have worked on similar seismic stability assessments for industrial steel storage systems and stacked structures using FEA and dynamic loading methods. I understand that the scope is limited to global stability verification of the 5-level rack stack, including overturning, sliding, uplift/separation between rack levels, and rack-to-floor interaction under seismic excitation. Component stress verification is explicitly excluded. My approach will include: Simplified rigid-body modeling of racks and 280 kg rolls Definition of rack-to-rack and rack-to-floor contact interactions Friction modeling based on published steel-to-concrete coefficients Selection and scaling of 7 NTC 2018 spectrum-compatible accelerograms from the ITACA database Time-history seismic analysis for the complete stacked configuration Evaluation of overturning, sliding, and separation risks Delivery of native PrePoMax (.pmx) or Mecway (.liml) files for future modifications Deliverables: FEA model files Time-history analysis results Stability assessment report Design assumptions and friction parameters Summary of seismic performance and safety margins I can begin immediately upon receiving the CAD models and project location data. Best regards, Hasan

The key challenge in this project is accurately evaluating seismic overturning, sliding, and rack separation behavior in a five-level stack where no mechanical connections exist between levels. Proper contact definition, friction modeling, and NTC 2018-compatible accelerogram implementation will be critical to obtaining meaningful results. My proposed approach is: 1. Review the supplied CAD assemblies and simplify geometry while preserving mass distribution and contact interfaces. 2. Build a dynamic model using rigid-body representations for racks and rolls, including rack-to-rack and rack-to-floor contact definitions. 3. Select, scale, and implement seven spectrum-compatible accelerograms in accordance with NTC 2018 requirements. 4. Perform time-history analyses and evaluate global stability criteria including overturning risk, sliding displacement, and level separation. I have extensive experience in structural and mechanical FEA, including contact-driven nonlinear simulations, dynamic loading, and stability assessments using commercial and open-source analysis environments. Deliverables: - Native simulation file (.pmx or .liml) - Technical report (PDF) - Model assumptions and design inputs - Result plots and stability assessment - Up to 2 revision rounds Scope is based on the current description. Component stress verification, fabrication activities, and additional analyses are excluded unless separately agreed. Final schedule will be confirmed after reviewing the source files. One technical question: have the design seismic parameters (ag, F0, Tc*) already been established for the project location, or should they be derived from the supplied coordinates?

Hello there, I’ve carefully reviewed your specifications, and I can take on the global stability analysis of the 5-level stacked rack system exactly as defined—focusing on overturning, sliding, and inter-level separation using time-history seismic analysis. I will model the system in PrePoMax/Mecway using the provided CAD files, applying the required simplifications (rigid welded racks, rigid roll bodies, and defined interfaces). The seismic input will be prepared using 7 NTC 2018 spectrum-compatible accelerograms from the ITACA database, with all scaling and combination steps clearly documented in the report. The workflow will include proper definition of friction assumptions at the base, rack-to-rack contact conditions, and clear justification of all design inputs. Alongside the structured report, I will also deliver the native project file (.pmx or .liml) so you can independently modify or replace accelerograms in the future as required. Before finalizing execution, I would like to confirm one detail: do you already have preferred friction coefficient values, or should I proceed with standard literature assumptions and clearly document them? Portfolio can be shared upon request. Best regards, Awais Razaq

I am a Mechanical Engineer with extensive experience in structural analysis, finite element modeling, and seismic performance evaluation of industrial structures. I can perform a detailed FEA simulation of your pallet rack system to assess its stability, stress distribution, deformation behavior, and overall structural integrity under seismic loading conditions. My expertise includes working with industry-standard software such as ANSYS, SolidWorks Simulation, and Abaqus to deliver accurate and reliable engineering assessments. For this project, I will develop a comprehensive finite element model of the pallet rack assembly, incorporating material properties, connection details, boundary conditions, and applicable seismic load cases. The analysis will evaluate critical structural responses, identify potential failure points, and verify compliance with relevant design standards and safety requirements. I can also investigate different loading scenarios and provide recommendations to improve rack performance and earthquake resistance. Upon completion, you will receive a detailed engineering report containing simulation results, stress and displacement plots, safety factor evaluations, and practical design recommendations. My focus is to provide clear, actionable insights that help ensure the pallet rack system remains safe, stable, and reliable during seismic events. I look forward to contributing my engineering expertise to the successful completion of your project.
