This study investigates four aspects associated with steel joist

supported wood floor systems: 1) acceptability, 2) prediction

of deflection, 3) prediction of frequency, and 4) effects of

diagonal bracing. Six full scale floor systems and two

two-joist floor systems were constructed in the laboratory.

Span length, joist spacing and diagonal bracing were the only

parameters modified for each floor. Four tests were

performed for each floor setup: heel drop impact, walking

perpendicular and parallel to the floor joists, static

concentrated load at midspan, and testing to determine

subjective evaluation.

Five acceptability criteria were investigated: Swedish

Building Technology Design Guide, Australian Standard

Domestic Metal Framing Code, Canadian Timber Floor

Criterion, Murray's Criterion, and Johnson's Criterion. The

results from these criteria were compared to the measured

results of each floor system. Four methods to predict vertical

deflection due to a static load at midspan were compared to

measured values of each floor system. The effect of diagonal

bracing on floor stiffness was also investigated. Results and

concusions were made for each aspect investigated.
