As soon as 2024 began, a major earthquake occurred in the Hokuriku region. We would like to express our deepest condolences to those affected by this. ・It is an old building, but we must keep in mind that it is weak because it is this type of building. ・There was a video of a 7-story building in the city collapsing sideways, but the building was made of reinforced concrete with a piloti on the first floor, a method often used for parking lots and stores. ・In apartment buildings with parking lots on the first floor, the walls have been increased and earthquake-resistant renovations have been made more common. ・The structure of a building is considered by dividing the forces acting on the building into three types: bending, axial force, and shear. ・It is expressed in terms of the specific strength and strength/specific gravity of the material alone, but the tensile strength of wood is about 2.5 to 3.2 times that of steel and about 235 times that of concrete. The compressive strength of wood is about 1.2 to 1.6 times that of steel and about 11.7 times that of concrete. ・Be careful of concrete buildings that have not been maintained since they were built.・When building a new wooden house, the seismic resistance grade is now 2 or 3 (legally 1), so it's fine when it's new. ・However, the adhesive strength of structural materials such as pillars and beams, especially in the case of structural laminated lumber, decreases year by year, and the strength decreases. ・Even solid wood that has been dried at high temperatures (KD lumber) has lost its oil content, so it is more susceptible to rotting than naturally dried materials. Even cypress will rot. ・The advantage of wooden construction is that the building itself is relatively light compared to concrete construction. ・The weakness of wooden construction is moisture and termites. ・Borate is not only effective against termites, but is also very effective against wood corrosion. ・Old Japanese houses = breathing is important. • Learn from G-Shock to make a house earthquake-resistant ~ [Shock] The stronger the earthquake resistance, the more likely it is to break?
