Shear wall aspect ratio reducing frame (ARRF)

a technology of reducing frame and shear wall, which is applied in the direction of building reinforcements, construction, building components, etc., can solve the problems of high labor intensity, large site preparation, and large height, and achieve the effect of reducing the force on the shear wall, increasing the shear capacity, and reducing the resistance of shear forces

Abstract

My invention, the Shear Wall Aspect Ratio Reducing Frame is a simple, economical, efficient, easy to install device that allows greater oppotunity and flexibility in the size and location of openings in the walls of wood frame constructed buildings particularly houses. The ARRF would replace the commercial, pre-fabricated systems now in use which are costly and inefficient labor-intensive shear wall devices. The ARRF achieves its goal by reducing the moment arm in the overturning equations that are used to determine the uplift forces in a shear wall. The ARRF reduces forces in walls rather than increase their bulk which is the strategic concept now in use throughout the design professions and the construction industry to solve the aspect ratio problem.

[0003] ā€œNot Applicableā€BACKGROUND OF THE INVENTION

[0004] This invention pertains to the field of residential wood frame construction. There is a challenge in wood frame construction to resist loads on structures generated by lateral forces, i.e. wind and earthquakes. Most region of the United States are confronted by one or the other and in most areasā€”both.

[0005] Lateral forces are typically resisted by shear walls in economical wood frame construction or, when the aspect ratio of two to one is exceeded Two being the heighth and one being the width, by pre-fabricated heavy duty ā€œstrong wallsā€. Due to the expense and complexity of strong wall assemblies, residential house designers try to avoid using walls that have an excessive aspect ratio. The...
