【117】ACTRAN里beam单元如何使用？

Q：ACTRAN里beam单元如何使用？

A：ACTRAN中beam单元用于模拟结构中加强筋。可以使用hyperbeam得到加强筋的属性，转换方式如下表：

ACTRAN	Hyperbeam
the elongation modulus E;	elongation modulus
the shear modulus G;	shear modulus
the solid density rs;	solid density
the area of the section A;	area of the section
the area moment of inertia Ixx with respect to axis y0;	Iy local
the area moment of inertia Iyy with respect to axis x0;	Ix local
the product moment of inertia Ixy;	Iyz local
the torsional constant Iz;	Torsional constant
the shear area factor Kx in plane xx0;	Ky
the shear area factor Ky in plane yy0;	Kz
the relative offset of the center of gravity along the x0 axis;	Yc
the relative offset of the center of gravity along the y0 axis;	Zc
the relative offset of the center of shear along the x0 axis;	Ys local
the relative offset of the center of shear along the y0 axis.	Zs local

Please be aware that the current implementation of the beam elements does not support the wrapping effect (deformation normal to the cross-section).
