Innovative thinking in engineering The Bank of America building in Managua,Nicaragua survived after a grand shock of 7.8 grade in 1972. The innovative thinking in design is that the passive control idea was adopted while the bracing between outer frame and inner frame were automatically failed which causes the stiffness of the structure dropped down and frequency decreasing to avoid resonance from the ground motion. 然过于地中心的羊土宣Innovative thinking in engineering • The Bank of America building in Managua, Nicaragua survived after a grand shock of 7.8 grade in 1972. • The innovative thinking in design is that the passive control idea was adopted while the bracing between outer frame and inner frame were automatically failed which causes the stiffness of the structure dropped down and frequency decreasing to avoid resonance from the ground motion
