Most houses in Japan are constructed of wood, and structural calculations that take into account earthquake and wind resistance are essential for their design. Especially for low-rise wooden houses, wall volume calculations and eccentricity considerations based on the Building Standard Law are important factors. This article summarizes the basic concepts in structural design of wooden houses and introduces the optimization of structural design of low-rise wooden houses using Grasshopper. It should be of interest to those involved in structural design and those interested in improving the efficiency of design methods.

This article presents an example of a design flow using an in-house design environment, with one specific design case study.

DFM PULSE, our vibration isolation solution, provides design solutions for vibration isolation devices for a wide range of components. Technical explanations will be given on the design of structural solutions to surging, which is a problem in vibration isolation structures.

Quasi-Zero Stiffness structure is known as a technology to solve the trade-off between stiffness, mass, and vibration isolation introduced in the previous article. A search for "Quasi-Zero Stiffness" will turn up several papers (e.g., [1], [2], [3]), so I will give an overview and introduce the solution in NatureArchitects.

DFM PULSE, our vibration isolation solution, provides design solutions for vibration isolation devices for a wide range of components. The article will introduce the basic statics and dynamics of why a metamaterial approach to vibration isolation may be necessary instead of an existing component.
