Abstract EN
In order to explore the impact of traffic environmental microvibration on buildings, this paper studies indoor vibration isolation, a method applicable to existing buildings.
The vibration isolation scheme is designed based on the residential buildings adjacent to metro lines in Shanghai.
By using the dynamic theory, the effective range of vibration isolation stiffness is analyzed.
The effectiveness of the indoor vibration isolation method is verified through theoretical calculations and comparison of field measurements before and after isolation.
A detailed numerical model is established to analyze the indoor isolation and the effect after parameter optimization from the slab thickness, filling material, and isolator stiffness.
The results show that the isolation effect is proportional to the thickness of the total slab thickness of the isolation system and inversely proportional to the stiffness of the isolator.
And when concrete is used as the filling material, the isolation effect is best.
The isolation effect of the midspan position is better than that of the wall-floor junction.
The vibration isolation effect is more obvious after the parameters are optimized.
With its convenient construction technology, short cycle, and low cost, this method is worth promoting.
