1You are a structural/facade engineer checking a task-owned synthetic SSC-09 facade wind, bracket, anchor, and tolerance package for one redrawn rainscreen elevation bay.2 3Use only the task-owned synthetic source pack values shown below for numeric grading. External EN 1991-1-4, ASCE 7, NVELOPE, PROFIS, Fixfast, Downer, and other rainscreen workflow routes shape the practice context only; they are not extra data sources for this instance.4 5## Scene6 7- Facade case ledger: `CASE-SSC09-FACADE-001`8- Redrawn facade elevation: `ELEV-09-REDRAWN-01`9- Wind criteria note: `WIND-09-CRIT-01`10- Facade pressure-zone schedule: `PRESS-09-ZONES-01`11- Bracket/support schedule: `SUP-09-BRACKET-01`12- Concrete anchor excerpt: `ANCH-09-CONC-01`13- Tolerance and setout note: `TOL-09-SETOUT-01`14- Facade fixing memo: `MEMO-09-FIXING-01`15 16The representative elevation bay has one body bracket row, one edge bracket row, and one corner bracket row. The bracket schedule has one fixed-point row for vertical dead load and two sliding-point rows for wind restraint and expansion. Preserve these fixed and sliding points in the memo.17 18Unit convention for this source pack:19 20- `kPa x m2 = kN` for these pressure-area load checks.21- All bracket and anchor demands and resistances below are in `kN`; do not convert them again before forming utilization ratios.22- Utilization ratios are dimensionless `kN / kN` values. For example, `2.16 kN / 2.8 kN` is about `0.77`, not `0.00077`.23 24## Wind And Pressure-Zone Basis25 26| Item | Value |27|------|-------|28| Basic wind speed | {{ basic_wind_speed_m_s }} m/s |29| Source-owned velocity pressure | {{ source_velocity_pressure_kpa }} kPa |30| Body-zone pressure coefficient magnitude | {{ body_pressure_coefficient }} |31| Edge-zone pressure coefficient magnitude | {{ edge_pressure_coefficient }} |32| Corner-zone pressure coefficient magnitude | {{ corner_pressure_coefficient }} |33 34Wind checks:35 36- Velocity pressure equals the `source_velocity_pressure_kpa` value from `WIND-09-CRIT-01`. The basic wind speed is retained as source context only for this synthetic instance.37- Body pressure equals `velocity_pressure_kpa x body_pressure_coefficient`.38- Edge pressure equals `velocity_pressure_kpa x edge_pressure_coefficient`.39- Corner pressure equals `velocity_pressure_kpa x corner_pressure_coefficient`.40- Use pressure magnitudes for the bracket and anchor demand checks. The redrawn source pack treats the governing facade action as suction, but grading uses positive demand magnitudes.41 42## Bracket And Anchor Basis43 44| Item | Value |45|------|-------|46| Bracket tributary width | {{ tributary_width_m }} m |47| Bracket tributary height | {{ tributary_height_m }} m |48| Facade dead load | {{ facade_dead_load_kpa }} kPa |49| Bracket horizontal resistance | {{ bracket_horizontal_resistance_kn }} kN |50| Bracket vertical resistance | {{ bracket_vertical_resistance_kn }} kN |51| Anchor tension resistance | {{ anchor_tension_resistance_kn }} kN |52| Anchor shear resistance | {{ anchor_shear_resistance_kn }} kN |53| Anchor embedment | {{ anchor_embedment_mm }} mm |54| Minimum anchor embedment | {{ minimum_anchor_embedment_mm }} mm |55| Corner anchor edge distance x | {{ corner_anchor_edge_distance_x_mm }} mm |56| Corner anchor edge distance y | {{ corner_anchor_edge_distance_y_mm }} mm |57| Minimum anchor edge distance | {{ minimum_anchor_edge_distance_mm }} mm |58| Corner nearest anchor spacing | {{ corner_nearest_anchor_spacing_mm }} mm |59| Minimum anchor spacing | {{ minimum_anchor_spacing_mm }} mm |60 61Bracket and anchor checks:62 63- Tributary area equals `tributary_width_m x tributary_height_m`.64- Zone wind load equals `zone_pressure_kpa x tributary_area_m2`.65- Dead load per bracket equals `facade_dead_load_kpa x tributary_area_m2`.66- The dead load result is already in `kN`; use it directly in vertical margin and anchor shear utilization checks.67- Corner bracket horizontal utilization equals `corner_wind_load_kn / bracket_horizontal_resistance_kn`.68- Corner bracket vertical utilization equals `dead_load_per_bracket_kn / bracket_vertical_resistance_kn`.69- Anchor tension utilization equals `zone_wind_load_kn / anchor_tension_resistance_kn`.70- Anchor shear utilization equals `dead_load_per_bracket_kn / anchor_shear_resistance_kn`.71- Combined anchor utilization equals `sqrt(anchor_tension_utilization^2 + anchor_shear_utilization^2)`.72- Governing utilization is the maximum of body anchor combined utilization, edge anchor combined utilization, corner anchor combined utilization, corner bracket horizontal utilization, and corner bracket vertical utilization.73- Anchor embedment margin equals `anchor_embedment_mm - minimum_anchor_embedment_mm`.74- Anchor edge margin equals `min(corner_anchor_edge_distance_x_mm, corner_anchor_edge_distance_y_mm) - minimum_anchor_edge_distance_mm`.75- Anchor spacing margin equals `corner_nearest_anchor_spacing_mm - minimum_anchor_spacing_mm`.76 77## Tolerance And Setout Basis78 79| Item | Value |80|------|-------|81| Nominal cavity depth | {{ nominal_cavity_depth_mm }} mm |82| Measured wall offset | {{ measured_wall_offset_mm }} mm |83| Minimum bracket projection | {{ minimum_bracket_projection_mm }} mm |84| Maximum bracket projection | {{ maximum_bracket_projection_mm }} mm |85| Required remaining tolerance allowance | {{ installation_tolerance_allowance_mm }} mm |86| Fixed-point rows | {{ fixed_point_count }} |87| Sliding-point rows | {{ sliding_point_count }} |88 89Tolerance checks:90 91- Required projection equals `nominal_cavity_depth_mm + measured_wall_offset_mm`.92- Projection margin equals the smaller of `required_projection_mm - minimum_bracket_projection_mm` and `maximum_bracket_projection_mm - required_projection_mm`.93- Fixed-point vertical margin equals `bracket_vertical_resistance_kn - dead_load_per_bracket_kn`.94- Governing row is the corner row when the corner combined anchor utilization controls the maximum utilization.95- Overall pass score is `1.0` only when governing utilization is no greater than 1.0, anchor embedment/edge/spacing margins are non-negative, projection margin is at least the required remaining tolerance allowance, fixed-point vertical margin is non-negative, and the corner row is governing; otherwise it is `0.0`.96 97## Output Format98 99Write a compact facade fixing memo to `/workspace/output.md`.
