<aside> 🆕
v1.11.0(2026.10.04)追加のコンポーネントです(OpenSees > PreProcess)。
</aside>
梁要素の剛域(節点から接続する部材のフェイスまで)を自動で求め,解析コンポーネントの入力 RZ(rigid zone)の形 [[Li, Lj, Asy, Asz, rigid],...] で出します。RZ は Elastic Analysis,ElasticAnalysis2,Elastic Analysis for N,Prescribed Displacement Analysis,Pushover,Nonlinear time-history analysis に繋ぎます。
入力データは以下の通りです(説明は Grasshopper のツールチップと同じ)。
R : [x1,y1,z1],...IJ : [No.i,No.j,material No.,section No.,angle],...l_vec : ... from EleVecP1 : depth of each section along the local z axis [m] (Cross-Sec Perf output P1; walls: the wall length)P2 : width of each section along the local y axis [m] (Cross-Sec Perf output P2; walls: the thickness)rigid sec : section Nos. of rigid elements (e.g. the rigid beams inside walls); they become rigid elements (stiffness x1000)A : section area of each section [m2] for the shear deformation (Cross-Sec Perf output A)kappa : shear shape factor: shear area = A / kappa (0: no shear deformation)level : 0: the beam lines are at the top of the beams (floor level; columns/walls get a rigid zone of the beam depth at the top), 1: at the beam centersfactor : factor for the rigid zone length (1.0: up to the face)
