New design of floor beams for low-rise construction

Abstract

We are reviewing one of the part of solution to problem of providing residential property for population. Construction price can be reduced due to the use of glued plywood floor beams. To simplify production technique and to reduce its price it has been offered to eliminate splicing of plywood walls and to apply beams with perforated walls. Stress-strain analysis and comparison of different design models behavior were made with photo elasticity method. Models of the optically-responsive material put in the strain viewer area and loaded with designed forces, allowed to observe real stress patterns. Models’ state of strain was evaluated with dial gauge.
