2026.10.10 (v1.23.0)

• Structural drawings (StrDrawing, not in the public edition): pile plans, GL / footings / piles in the elevations (pilecut for the cut symbol), a pile list file (pile list and sketches, footing list, column-pile joint list, soil columns); inputs pilelayers / pilelist / soil, opt piles, gl, pileelev, pilecut. RC wall elevations: wall / beam ends extended to the far face of the orthogonal members, orthogonal members behind drawn with dotted envelopes.
• Author information in the PDF files and the plug-in: Kindai University.

2026.10.10 (v1.22.0)

• From this version the public edition does not include: section design checks other than SteelCheck / TimberCheck / RCBeamCheck / RCWallCheck, PDF / TeX reports (PDF OUTPUT of the four checks, PDF of Pushover / NLTH, SteelCheck / TimberCheck / CLTCheck PDF Output, AnalysisResultPDF series, DataOutput), structural drawings (StrDrawing), Eccentricity / Eccentricity2, pile checks (PileHorizontal, PileCapacity, PileFooting, PileFrameCheck) and the RC wall limit strength / section checks (WallLimitStrength, WallAxisForces, WallSectionCheck). Pages of these components are marked 🔒. Modelling, loads, analyses (elastic, GNL, Pushover, time history, NLTH), visualization, SoilData / PileList / PileModel and the RC wall models are unchanged. A .gh using a removed component opens with that component shown as missing.

2026.10.09 (v1.21.0)

• Pile (杭): integrated model of the superstructure and the piles. PileModel (new) adds the piles (beam elements), the soil springs kh·B·l, the vertical spring at the pile tip and the footings (rigid elements) to the input of Elastic Analysis, removes the supports and adds the horizontal force of the foundation to FX / FY — with the same SoilData / PileList / pile point user texts as the separated model. Pile points may be placed e.g. on the top of the foundation beams: they are matched to the model node at the same plan position. PileFrameCheck (new) checks the pile body (long / short term, N-M), the bearing capacity and the footings / pile head joints with the results of the integrated analysis; three PDF / TeX reports.
• WallFrameModel: nodes at T-junctions of beams on the through beam; floor heights (average of the beam centers) and the rigid zones of the walls from the actual tops of stepped wall beams / foundation beams; columns and braces of the added frame (e.g. timber posts on the wall beams) keep their ends at the face with a rigid element from the floor node, so their pins are at the face; output layer includes the levels of the added frame above the walls (e.g. the roof of a timber 2nd story).
• RcBeamCheck / RCWallCheck / RcColumnCheck / MerikomiCheck: PDF and TeX reports in the same format as TimberCheck / SteelCheck (title, design policy with equations (input cover), materials, summary, column sheets with 4 members per page). TeX tables in sans serif (gothic); each member group of the section sheets fits on one page (also TimberCheck with 54 / 90 columns). RCBeamCheck / RCWallCheck: long-term wft of the stirrups / horizontal bars is 195 also for D19–D25 (was 215).
• RcColumnCheck (calculation reviewed, ratios change): allowable moment from the cracked section by searching the neutral axis (different bars on the two faces; same as the RC standard formula for symmetric bars; nominal bar areas), axial force at each position (all positions used the i-end force), Young's modulus ratio n from Fc, short-term shear checked for damage control (QL + QE) and safety (QL + n·QE), j of the weak axis from its own depth. Fixed: short-term boundary with the long-term fc, covers of the bottom / left faces, L−Y shear with the Qa of L+Y, long-term hoop wft 215, negative pw − 0.002, negative / infinite Ma beyond the axial range, no PDF with 90 columns, stop when b, D are missing. New check of the structural rules (bars ≥ 4, ≥ D13, pg ≥ 0.8 %, hoops ≥ 9 mm, pw ≥ 0.2 %, spacing 100 / 150 mm, smallest side ≥ L/15, long-term N/(bD·Fc) ≤ 1/3). QaL / QaS have 6 values (both directions). New inputs TeX, cover.
• MerikomiCheck (reviewed): default index = vertical members only (beams were checked with their axial force), the end with the larger long-term compression (was the i end), new inputs type (0: sill etc. 1.5Fcv/3 as before, 1: others 1.1Fcv/3) and Cm (reduction factor), N.G. when the area minus the tenon is 0 or less (was O.K.).
• Cross-Sec Perf: the warning "P1-P4 have fewer items than S" is shown only when a value needed by the section type is missing (■ needs P1, P2 only).
• TimberCheck / SteelCheck: PDF and TeX reports with the PDF OUTPUT button (cover with the allowable stresses and the check equations, material table, summary, tables per member, case and position; TimberCheck also shear walls / floor diaphragms from KABE_W), new inputs outputname, TeX, secname, matname; radio buttons. Fixed (ratios change): with sec_f of L, X, Y the L−X / L−Y shear forces and moments were |L| − |E| (unconservative where L and E act in the same direction); now |L ± E| with signs (also CLTCheck). SteelCheck: the lateral-buckling fb of H sections used F instead of ft = F/1.5 in {1 − 0.4(lb/i)²/(CΛ²)}; the axial force at the center for L−X / L−Y and the j-end combination of L−Y are fixed.
• AssembleWalls: input layer (Rhino surfaces with user text bairitsu or K and rad: plywood shear walls / floor diaphragms as panels), warning for corners not on nodes, outputs info / Surf. Elastic Analysis etc.: the force of the second diagonal of a panel used the area of the first one (only non-rectangular panels).
• PileFooting / PileList / PileFrameCheck: hakama bars of the footings (default D13@300); with uplift of a pile the top of the footing is checked with the hakama bars like the bottom bars. Default diameter of the circle of the pile head bars = pile head diameter + bar diameter.
• PileList / PileFrameCheck: column-pile joints instead of footings — a steel pipe pile and a steel column connected directly by a top plate, a base plate and high-strength bolts (new tab “柱と杭の接合部”: column section, plates, bolts, PCD, α, h; user text joint). PileFrameCheck checks the full-strength connection (Mu = Σ Tb·(xi + c) + N·c ≥ α·Mp of the column / pile, Qu ≥ α·2Mp/h) and the allowable stresses (bolt tension / shear, plate bending); new output joint and report name_joint.pdf with plan / section drawings. PileList draws the plates, bolts and a column stub in Rhino. Steel pipe grades SKK490 / STK490: F = 315 (was 325).
• ReadBeam2 / Cross-Sec Perf: haunched beams (RC and steel). Line user text seci / secj (end section No.) and hi / hj (haunch length [m]); one of them only: one-sided haunch. ReadBeam2 divides each haunch into haunch div elements (default 10) with the dimensions P1–P4 interpolated linearly at the middle of each element (output haunch), and Cross-Sec Perf adds the interpolated sections from haunch No. (input haunch). PileModel: input B is optional.
