Seismic performance optimization of reinforced concrete shells generated by the force density method: A nonlinear multilayered approach

The construction of concrete shell roofs in Mexico has declined owing to seismic vulnerability and slenderness effects. Traditional form-finding guarantees static equilibrium under self-weight alone and remains inadequate under seismic demand, where stiffness degradation and stress reversal govern the response. Three f...
