Design and construction of plain and reinforced concrete structures by working stress and limit state methods.

Issued by BIS · Governs RCC Design

Provisions most often examined

  • Limit state of collapse (flexure): \(x_{u,\max}/d\) limits by steel grade
  • \(0.36\,f_{ck}\) stress-block constant; 0.42 depth factor
  • Durability & minimum cover requirements
  • Development length \(L_d = \phi\,\sigma_s / (4\,\tau_{bd})\)

These are the provisions that recur in ESE, GATE and SSC JE question papers, not a complete list of the code's clauses. Mock Test Mitra is a practice platform, not a standards body — read the code itself for authoritative text.
