Synonym judgment was split into 3 conditions varying the type of word (51 high-frequency concrete words [mean frequency = 18 267; mean imageability = 4.69], 51 low-frequency concrete words [mean frequency = 1897; mean imageability = 4.33], and 51 abstract/low imageability words [mean frequency = 2035; mean imageability = 3.24]).
Compared to conventional concrete, the frequency of RAC with 100% RCA reduced by 11% and its damping ratio increased by 17%.
Then it includes the definitions of the concrete techniques (frequency and duration) and a checklist that has been created to ascertain how and to what extent the intervention has been delivered as specified.
Synonym judgment was split into 3 conditions (20 items for each cell) varying the type of word (20 high-frequency concrete words, 20 low-frequency concrete words, and 20 abstract/low imageability words) but matching decision times.
In concrete rule sequences, frequency of the first tone was 900 Hz; in abstract rule sequences, it was chosen randomly from 10-Hz steps in the interval of 600 to 1200 Hz (Fig. 4).
The saw-tooth shaped wall diffuser profile in the Chamber Hall was designed using glass-fiber reinforced concrete for mid-frequency sound diffusion.
In this study, which is limited to the linear-elastic behavior, emphasis is given to study the torsional response of a reinforced concrete frame when excitation frequencies are close to the modal frequency associated with the first torsional mode of the system (buildings + soil).
An impact resonant apparatus was used to measure the fundamental longitudinal frequency of concrete, mortar and paste specimens of the size Ø50 × 75 mm.
The mechanism which damages plain concrete specimens under high frequency fatigue loads was analysed and a non-linear accumulative fatigue formula that causes the damage was proposed.
An artificial neural network (ANN) based approach is presented for the assessment of damage in prestressed concrete beams from natural frequency measurements.
At frequencies higher than the slab resonance frequency, the concrete slab uncouples from the underlying soil and the transfer of vibrations is reduced.
