Local Tensile Strength of Connection Between H-Steel Beam Flange and Concrete-Filled Circular Column Tube with Through Diaphragm

This paper focused on investigating local tensile strength of connection between steel beam flange and concrete-filled circular column tube with through diaphragm. Three specimens were designed and tested to failure, and the structure behavior was studied by experiment and FEM analysis. On the basis of the results obtained, an estimation for local plastic and ultimate strengths of the connections using yield line theory was attempted, which results in a good prediction.

土石薄膜注浆桩施工工艺及单桩检测

薄膜混凝土压注桩采用的是一种全新的施工工艺。它利用高压灌注,将混凝土灌入预先压入土层的注浆管,形成土石薄膜压注桩。与以往的灌注方法相比,土石薄膜压注桩中混凝土的水泥浆液虽然没有渗入土中发生粘土固化,但桩对天然地基的挤密和压实作用更强。所以其承载能力远远大于摩擦桩,同等承载力下可大大缩短桩长。这种施工方法,免去了预先成孔的复杂工序,工艺简单,成桩速度快,造价低,具有很高的推广价值。
