rigid-frame bridge
Civil engineering term for a bridge whose superstructure and piers are rigidly connected, forming a continuous frame.
This rigid-frame bridge is designed to be earthquake-resistant.
I explained the structure of a rigid-frame bridge using a model.
From ラーメン (Rahmen, German for 'frame') + 橋 (bridge). The term ラーメン in this context is unrelated to the noodle dish.
