| 摘 要： | 低高度钢筋混凝土T梁建筑高度低，能节省较多的工程建设费用，但在实际应用中逐步显露出刚度过低问题。为了研究16m低高度T梁桥的运营状况、安全性和加固对策，选取某桥二孔进行低高度T梁挠度、振幅和加速度等主要动力性能测试，发现桥跨及桥墩横向刚度较低，需采取适当加固、补修措施，提高横向刚度。

| Abstract: | Owing to the lower construction cost of low-height reinforced concrete T-beams,they used to be widely used in railway bridges.But with the development of the cause of railway transportation,low-height reinforced concert T-beams begin to show their shortcoming of insufficient rigidity gradually.To study the operating behavior,safety of and strengthening measures for low-height T-beam bridges,two spans of 16-m low-height reinforced concert T-beams of a ceratin bridge are tested to find their major dynamic beh... |
