# Diamond stirrups

**Diamond Stirrups** are a special type of reinforcement stirrup used for **square columns**. Unlike traditional rectangular stirrups, diamond stirrups form a **diamond-shaped loop** around the column reinforcement, providing improved confinement and aesthetic symmetry.

{% hint style="info" %}
Currently, **Diamond Stirrups** are **supported only for square column configurations**.

***

Diamond stirrups can only be generated under specific reinforcement conditions.\
They are **conditionally enabled** based on the reinforcement layout of the **Front** and **Bottom** faces of the column.

***

Diamond stirrups will be generated **only if one of the following conditions is met:**

* #### **Condition A – Reinforcement Count Rule**

The **Front** or **Bottom** reinforcement must satisfy at least one of the following:

* The number of bars is **greater than or equal to 3 (≥ 3)**, **or**
* The number of bars is an **odd number** (e.g., 3, 5, 7, ...).

**Example:**

| Face   | Number of Bars | Diamond Stirrup Allowed? |
| ------ | -------------- | ------------------------ |
| Front  | 2              | ❌ No                     |
| Bottom | 4              | ❌ No                     |
| Front  | 3              | ✅ Yes                    |
| Bottom | 5              | ✅ Yes                    |

* #### **Condition B – Center Tie Rule**

Diamond stirrups may also be generated if they are tied to a center bar.

This rule overrides the reinforcement count rule.\
If a **center bar (Front/Back) -** connection exists, **diamond stirrups can be generated** regardless of bar count.
