This product is an experimental model designed to investigate the generation of wind caused by buildings (mainly high-rise) and the impact of that wind on the surrounding area. It consists of a target building model called the "Planned Building Model" and a disk called the "Surrounding Model," which reproduces the surrounding elements (buildings, terrain, trees, etc.). The "Planned Building Model" focuses on reproducing the shape components that directly affect the wind, while the "Surrounding Model" is created by integrating map information, aerial photographs, and detailed information obtained from thorough field surveys. Please feel free to contact us if you have any inquiries. 【Features】 ■ Planned Building Model - Focuses on reproducing the shape components that directly affect the wind - Also reproduces the ventilation areas inside the building ■ Surrounding Model - Created by integrating map information, aerial photographs, and detailed information obtained from thorough field surveys - If there are large buildings in the vicinity, relevant materials will also be obtained and incorporated into the model *For more details, please refer to the PDF document or feel free to contact us.

In recent years, buildings have featured unique exteriors and innovative designs such as full glass facades, making it difficult to conduct displacement and stress analysis of various components solely through computer simulations in response to external forces like earthquakes and typhoons. Our testing equipment allows for the direct application of deformations and loads equivalent to those caused by earthquakes and typhoons on actual building materials, enabling the confirmation and evaluation of displacements, stresses, and water leaks. The "Dynamic Wind Pressure Testing Device" is placed over the seismic testing specimen, where wind pressure loading and water spraying are conducted within a pressure box. The "Seismic Testing Device" attaches a test wall to a virtual slab section corresponding to the building's beams, allowing for the reproduction of displacements between different floors during testing. 【Seismic Device Specifications】 ■ Test Specimen - Types: PC, stone, tile, aluminum materials - Weight: Max 40TON - Dimensions: W8–10m, H10–13m, L part D2.5–3.6m ■ Test Items: In-plane, out-of-plane, simultaneous in-plane and out-of-plane, corner tests, research on construction methods ■ Optional Tests: Local wind and rain, thermal irradiation tests, etc. *For more details, please refer to the PDF document or feel free to contact us.
