# Continuous Beam RC Design App - Thai Standards

A comprehensive continuous beam reinforced concrete design application using finite element analysis with Thai reinforcement standards.

## Features

- **Finite Element Analysis**: Accurate structural analysis for up to 10 spans
- **Thai Standards**: Reinforcement design using Thai steel grades (fy = 4000 ksc)
- **Multiple Loading Types**: 
  - Distributed loads (kN/m)
  - Point loads (kN)
  - Mixed loading patterns
- **Comprehensive Results**:
  - Bending Moment Diagrams (BMD)
  - Shear Force Diagrams (SFD)
  - Detailed reinforcement layout with optimized bar spacing
  - Enhanced stirrup layout with precise spacing dimensions
- **Professional Output**: Detailed design reports and visual diagrams

## Usage

1. **Set Beam Properties**: Width, depth, concrete strength (f'c), steel strength (fy), cover
2. **Add Spans**: Enter span length and distributed load
3. **Add Point Loads** (optional): Use format `position,load; position,load`
   - Example: `2.0,50; 4.0,30` means 50kN at 2m and 30kN at 4m
4. **Design Beam**: Get complete analysis and design results
