Comfort Behavior of High Performance Floor Based on Single-Jump Excitation Mode Considering Time–Space Effect

Abstract

Because the traditional analysis methods cannot directly describe the comfort behavior of high performance floor through the dimensions of time and space, this paper presents a new method to derive Dirac delta functions and governing differential equations to assess its comfort behavior. On the basis of this, an improved single-jump excitation model is proposed for comfort behavior analysis. In addition, the paper analyzes distribution characteristic of sensitive parameters for the high performance floor. The results show that the peak acceleration is concentrated in the middle of the high performance floor, and then the acceleration response gradually weakened to the two sides, and its degree of weakening is greater along the two corners of the floor model from its spatial and temporal distribution characteristics. In future, it is recommended to change the strength grade of concrete materials to improve its comfort behaviors. The study also demonstrates the strong applicability of improved single-jump excitation model as an effective approach to analyzing the comfort behavior of high performance floor.
