Question 1

What is काष्ठ छत शहतीर (Timber Roof Joists)?

Accepted Answer

Kāshtha Chhat Shahteer (Timber Roof Joists), or *dāru chhat shahteer* (दारु छत शहतीर) in Sanskrit, are structural wood members crucial in Indic heritage architecture [1]. Predominantly sourced from forests across the Western Ghats, Central India, and the Himalayan region, these joists historically utilized hardwoods like teak (*Tectona grandis*) and sal (*Shorea robusta*) for their superior density (500-800 kg/m³) and bending strength (40-100 MPa) [2]. Traditional construction methods, documented in ancient *Shilpa Shastras*, emphasized proper seasoning to achieve a moisture content of 12-15%, minimizing warping and decay. The Maurya, Gupta, and Mughal dynasties extensively employed these joists in palaces, temples, and forts. Conservation efforts at sites like Ajanta and Ellora necessitate careful assessment of wood species, decay mechanisms (fungal attack), and appropriate consolidation techniques. Thermal conductivity ranges from 0.1-0.2 W/mK. Restoration often involves replacing deteriorated sections with sustainably sourced timber, treated with traditional preservatives like neem oil, ensuring structural integrity and preserving the aesthetic character of heritage structures [3].
