Fire resistance of reinforced concrete semi-continuous

hollow core deck structures at frame houses

Keywords: fire, fire resistance, reinforced concrete, semi-continuous slabs,

bearing capacity, ultimate strains.

The purposes of work are: to get fire resistance experimental data for new

reinforced concrete semi-continuous hollow core deck structures at frame houses; to

determine failure mechanism and ultimate stress-strained state of loaded structures

under standard-rate fire exposure; to work out design proposals for its fire resistance

evaluation.

Methods of research. The standard and full-scale tests suite of frame fragments

with semi-continuous hollow core deck structures was used. The obtained data was

theoretically analyzed.

Obtained data and novelty. The standard and full-scale fire tests were conducted.

The fire resistance of semi-continuous hollow core deck reinforced concrete structures

was studied and failure mechanisms were revealed. The calculation grillage beam model

for fire resistance assessment and stressedly-deformed criteria was developed for

concerned structures.

Usage recommendations. Developed test procedures for fire resistance

assessment of full-scale frame houses fragments can be used for other structures,

including various combinations of precast and cast-in-situ elements. The results of this

research are recommended to use in organizations of engineering and construction of

the Republic of Belarus in designing of fire resistant reinforced concrete semi-

continuous deck structures, as well as in educational process at relevant institutions.

Application. Engineering and construction organizations, higher educational

establishments.
