Layout Of Multi-tall Frame-shear Structure Lateral Stiffness On Anti-shear-torsion Characteristic Effect

In the complex architectures the incorrect layout of their horizontal force resistant members results in unevenness of their shear-torsion effect under horizontal loads. Although mono-architectures, regular and symmetric structures, different points of shear-wall give rise to different torsion actions. It is without saying that shear-torsion characteristic effect in the complex architectures is difficult to avoid .It is put forward that Classic Mechanics-Based story-force equality method and is derived from story-displacement coordination, elastic-physics relation of internal-force and displacement, static-equalityCondition in this thesis. Programmed on the grounds of this, and analyzed shear-torsion internal force and displacement characters (comparing with the result of program SATWE)of "L" planes and "Z" planes structures under wind loads(basic wind pressure 0.35kN/m~2) and7° earthquake action. According to this, aimed at reasonably arranging lateral stiffness, and improving the internal force distribution of anti-lateral force members。...
