What it does

Concrete Wall Design is an agent skill from h30190/HJPLUS_Taiwan_Architect_KB. This skill should be used when an architect or structural designer needs to verify PDF-backed concrete wall requirements such as minimum wall thickness, high-shear minimum reinforcement, bar spacing, and opening reinforcement in Taiwan's concrete structure design code.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: claude-code,opencode,agent-skills

It sits in Documents & Office, covering PDF. The repository describes itself as: 一個開源的台灣AEC產業知識庫,只要你願意共享經驗與知識就歡迎加入我們. The licence is CC-BY-SA-4.0.

When your agent uses it

  • Tasks that involve PDF

Example prompts

  • “/concrete-wall-design”

Requirements

  • Python 3
  • Compatibility (from SKILL.md): claude-code,opencode,agent-skills

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Add supplementary bars around the opening so that the interrupted reinforcement is replaced
  2. Double-layer walls: add at least 2 D16 bars in both directions around the opening
  3. Single-layer walls: add at least 1 D16 bar in both directions around the opening
  4. Anchorage must develop fy at the opening corners

What it can do on your machine

Read from SKILL.md and the folder at commit 35ed06e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are python).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    claude-code,opencode,agent-skills

    From compatibility in the SKILL.md frontmatter.

Context cost

Concrete Wall Design loads about 1.8k tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 746 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Concrete Wall Design

Overview

Design requirements for reinforced concrete walls in Taiwan, limited here to clauses directly verified against the uploaded PDF: minimum wall thickness, high-shear minimum reinforcement, spacing limits, and opening reinforcement. Special seismic-wall and boundary-element checks remain chapter references only unless directly transcribed from Chapter 18. For cover and splice fundamentals, see concrete-general-requirements.


Section 1: Wall Classification

1.1 By Function
TypePrimary LoadDesign Focus
Bearing wall (承重牆)Axial (gravity) loadsAxial capacity, slenderness
Structural wall (結構牆 / 剪力牆)Lateral (seismic/wind) in-plane shearShear capacity, Chapter 11 and Chapter 18 checks
Retaining wall (擋土牆)Earth pressure (out-of-plane)Refer to foundation and retaining-wall clauses when applicable
Non-structural wall (非結構牆)Self-weight onlyMinimum reinforcement, crack control
1.2 By Reinforcement Layout
TypeConditionMinimum Layers
Single layerGeneral wall cases per detailing layout1 layer when permitted by design and detailing clauses
Double layerWall thickness > 25 cm, except stated exceptions in 11.7.2.32 layers near each face

Section 2: Minimum Wall Thickness

2.1 Bearing Wall Minimum Thickness

$$h_{wall} \geq \max\left(\frac{l_c}{25},\ 100\ \text{mm}\right)$$

Where lc = unsupported height or length (whichever is shorter).

For a wall with clear height = 3000 mm: h_min = 3000/25 = 120 mm

Source: 11.3.1.1, Table 11.3.1.1.

2.2 Shear Wall Minimum Thickness
  • Non-seismic: same as bearing wall (lc/25, min 100 mm)
  • Special structural walls: follow Chapter 18 requirements directly

Section 3: Minimum Reinforcement Ratios

3.1 Minimum Vertical Reinforcement (縱向鋼筋比 ρl)

$$\rho_l = \frac{A_{sv}}{A_g}$$

For general walls with low shear demand, minimum vertical reinforcement must be taken directly from Table 11.6.1.

For higher shear demand, the verified requirement is:

$$\rho_l \geq 0.0025 + 0.5(2.5 - h_w/l_w)(\rho_t - 0.0025)$$

and not less than 0.0025.

Source: 11.6.2(a).

3.2 Minimum Horizontal Reinforcement (橫向鋼筋比 ρt)

$$\rho_t = \frac{A_{sh}}{A_g}$$

For general walls with low shear demand, minimum horizontal reinforcement must be taken directly from Table 11.6.1.

For higher shear demand, the verified requirement is:

$$\rho_t \geq 0.0025$$

Note: When shear demand is high, use the Chapter 11.6.2 equation:
$\rho_l \geq 0.0025 + 0.5(2.5 - h_w/l_w)(\rho_t - 0.0025)$ and $\rho_t \geq 0.0025$.

Source: 11.6.2(b).

3.3 Maximum Bar Spacing

For cast-in-place walls:

  • vertical bar spacing $s \leq \min(3h, 45\text{ cm})$
  • horizontal bar spacing $s \leq \min(3h, 45\text{ cm})$

If in-plane strength requires shear reinforcement:

  • vertical spacing $s \leq l_w/3$
  • horizontal spacing $s \leq l_w/5$

If wall thickness is greater than 25 cm, distributed reinforcement in each direction must be in at least two layers near the wall faces, except for the exceptions listed in 11.7.2.3.

Source: 11.7.2.1, 11.7.3.1, 11.7.2.3.


Section 4: Opening Supplementary Reinforcement (開口補強)

4.1 Opening Reinforcement Rules Verified from the PDF

For each interrupted bar:

  1. Add supplementary bars around the opening so that the interrupted reinforcement is replaced
  2. Double-layer walls: add at least 2 D16 bars in both directions around the opening
  3. Single-layer walls: add at least 1 D16 bar in both directions around the opening
  4. Anchorage must develop fy at the opening corners

These requirements are taken from clause 11.7.5.1.

Source: 11.7.5.1.

Section 5: Special Seismic Wall Requirements

Special structural walls, boundary elements, and other seismic wall detailing must be checked directly against Chapter 18. This skill intentionally does not retain unverified boundary-element trigger formulas.


Section 6: Splice and Development Checks

Wall bar development and splices must be checked directly against Chapters 25.4 and 25.5, plus Chapter 18 when the wall is part of the seismic-force-resisting system.
