  1. Strip - shape underground structures such as the tunnels and tubes for various uses can be treated as a beam on elastic foundation under earthquake condition ， although there exists soil - structure interaction ， the foundation soil vibration is dominant in other words ， analysis of earthquake response of the soil is essential to this end ， simplified models ， ( i. e equivalent mass system models based on some equivalence criteria ) are proposed ， instead of a general 3 - d continuum model in this study ， equivalence criteria are proposed and the simplified models are compared the single - mass - string model is proved to be valid and therefore applied to the analysis of earthquake response of the pearl river immersed tunnel

    條裝地下結構如隧道、各種埋設管道等一般可看作彈性地基梁進行靜力及動力分析在地震條件下，結構與土相互作用，但土的振動成為主要因素為分析土的地震響應需把基土這一三維連續體作簡化處理，簡化成為等效多質點模型本文著重探討這種簡化模型的建立方法，推導等效方程，通過幾種簡化體系的分析比較，論證單質點串體系的合理性，並將其應用到廣州黃沙芳村珠江水下隧道工程的地震響應分析，為抗震設計提供依據
  2. The sections " shape of the beam in the steel structure is mostly i. with thinking of the strength factor, it ' s necessary to make the beam web high and thin

    鋼結構的梁截面多為工字型，從強度方面考慮梁腹板宜做得高而薄。
  3. Based on the investigation of research and application of concrete - filled tubular column to steel beam connections in china and abroad, according to engineering practice, six full - size specimens that the joints composed by concrete - filled square tubular column and i - shape steel beam divided as a and b groups have been tested under cyclic - loading in this paper. the three specimens of group a are connected by bolt - weld and the group b connected by welded at the end of beams

    本文在總結分析了國內外關于鋼管混凝土框架節點研究與應用現狀的基礎上，以實際工程為背景，在國內首次進行了a 、 b兩組共6個足尺節點試件的低周反復循環加載試驗，其中a組三個試件梁端採用栓-焊連接； b組三個試件梁端為全對接焊接。
  4. It analyzes the dynamic response of many different damage cases of simple i - shape beam structure and discusses their influences to natural frequency and modal curvature. it is found that the natural frequency and modal curvature can be used in identifying the severity and location of structural damage respectively. dynamic response of some real beams are measured and compared to the results analyzed by computer, it is found that there are some differences between them and the main reason is the error caused by modeling

    2 .針對土木結構中最為常見的梁式結構，對簡支工字鋼梁的多種不同損傷工況的動力特性進行了有限元模擬分析，研究了損傷對頻率和模態曲率的影響，發現固有頻率變化率和模態曲率的變化分別可以用於損傷程度和損傷位置的識別;在實驗室中實測了幾種工況的鋼梁的振動模態，發現實測結果與計算結果有一定的差異，分析其原因主要是模型誤差和噪聲影響。
