title: 1:100 Scaled Buildings with Perpendicular Surfaces
title: in Wind Loads on Multi-Level Roof Buildings

description: The experiment focused on the study of wind pressures on various scaled building models in a wind tunnel setting. It was conducted on different building models, each designed to reflect specific structural configurations and architectural elements, such as stepped roofs, U-shaped buildings, podium structures, and low-rise buildings with carport extensions.  The methodology included conducting wind tunnel experiments on 1:100 scale models of various building designs. These models were placed in the wind tunnel, and wind pressures were measured at all angles from 0 to 360 degrees in 15-degree increments. This comprehensive testing approach provided a broad dataset on how different building shapes and designs react to wind forces. The dataset is organized in five categories: The “Model Configurarion: Model Drawings" category contains 13 PDF files featuring plans and 3D schematic views, along with dimensions of the models. The “Sensor Information Pressure Tap Coordinates” category  includes 13 Excel files that provide the coordinates of pressure taps on each model. The “Event: Pressure Data” category is comprised of 13 subfolders, each containing 24 Excel files documenting pressure time histories for each wind direction, ranging from 0 to 360 degrees in 15-degree increments. The “Event: Wind Speed Data" category contains two Excel files with wind speed time histories at 100 mm and 150 mm heights. The "Project Report" folder houses a comprehensive report on the entire project.
description: This dataset includes files from an extensive wind tunnel study of stepped-roof buildings conducted at the Wall of Wind facility at Florida International University. The aim of the study was to clarify the key factors that affect aerodynamic forces on complex architectural shapes. While ASCE7-22 offers a guideline for wind loads on building components and roofs, it falls short of providing the detailed data needed by engineers to calculate wind loads on the surfaces of stepped-roof buildings. This study  fills that gap. The main subject under investigation was the impact of wind loads on different building geometries such as stepped roofs, U-shaped buildings, podium structures, and low-rise buildings with carport extensions. This involved a detailed examination of how various structural features influenced wind pressure distribution, with a specific emphasis on understanding the behavior of wind forces on these models. The outcomes include a series of detailed findings on wind pressure coefficients for each building model. These results offer insights into the wind load characteristics for different architectural forms, contributing to a better understanding of structural behavior under wind forces. The study findings will furnish additional data to enable engineers and scholars to more accurately assess and comprehend wind loads on buildings with multi-level roofs.  The dataset includes diagrams of each model’s geometry and wind pressure data. The data highlighted key areas where wind pressures were most significant and how different building features either mitigated or exacerbated these pressures. The data gathered from this study can be reused in multiple ways. It can serve as a reference for designing wind-resilient buildings, particularly in regions susceptible to strong winds or hurricanes. The empirical data can also aid in validating and refining computational models for predicting wind loads on buildings. Additionally, it can be used in academic research for further exploration into wind engineering, urban planning, and architectural design, potentially leading to innovations in building safety standards and construction practices.
