The lateral distributions of a signal, a response of scintillation detectors, have been simulated for vertical giant air showers in terms of the quark-gluon string model. Simulations have been carried out with the help of the suggested 5-level scheme. The estimated lateral structure function is more steep than the standard function used at the Yakutsk array to interpret data. At the same time this distribution of a signal coincides rather well with the lateral structure function observed at the Yakutsk array for experimental data sampled with the help of the Cherenkov radiation. The more steep function used to interpret data would result in increasing a number of giant air showers with energies above the threshold of the Greizen-Zatsepin-Kuzmin effect. The dependence of a signal at 600 m from the shower core for the vertical giant air showers on the energy of the primary particles have been also estimated.
