ABSTRACT. The level of seismic hazard to high-rise buildings is very great. The design of structures that can resist shock is always a topic that attracts many scientists to participate. One of the simplest methods to increase seismic resistance is to place a hard stratum in a frame structure. In this study, the effective working position of two hard floors in reinforced concrete structures of multi-storey houses will be analyzed. The research just stops at technical evaluation level, not considering economic indicators. The effectiveness of research through survey by numerical methods, simulating works subject to seismic impact is calculated according to TCVN 9386: 2012 and dynamic method by time domain.

KEYWORDS. stiff – storey, high - rise buildings, time history, earthquake.
