［摘要］以重慶市某小學(xué)體育館大跨度預(yù)應(yīng)力次梁樓蓋為研究對象，通過施加多種人致荷載進行振動實測，研究該樓蓋在人致荷載作用下振動響應(yīng)規(guī)律，對比國內(nèi)外基于加速度振級、結(jié)構(gòu)基頻、加速度的舒適度評價標準，選取適用于該類型樓蓋的舒適度評價標準。實測初步證明，在梁底增設(shè)減振底板能有效提高該類型樓蓋的舒適度。

Abstract:The large-span prestressed secondary-beam floor in primary school gymnasium in Chongqing was taken as the research object. Vibration field measurement was conducted by applying various man-induced loads to study the vibration response law of the floor under the action of the man-induced loads. By comparing the serviceability evaluation criteria based on acceleration vibration level, structural fundamental frequency and acceleration at home and abroad, the serviceability evaluation criteria applicable to this type of floor were selected. Field measurement preliminarily proves that adding a damping bottom plate at the bottom of the beam can effectively improve the serviceability of this type of floor.
Keywords:gymnasium; large span prestressed secondary-beam floor; vibration response; serviceability evaluation; damping bottom plate
