Abstract Steel-Concrete composite Panel (SCP) broadly used in storage tanks are modularized construction members that are made by placing concrete within two exterior steel plates. Placing of concrete, however, usually develops very high pressure which may cause excessive initial deformation on the exterior steel plates, and the developed deformation will affect the ultimate resisting capacity of the SCP member by an increase of instability in the steel plates. Nevertheless, the influence of the steel plate deformation on the evaluation of the ultimate resisting capacity has not been systematically reviewed. Especially since the ultimate resisting capacity of the steel plate is deeply related to the stud spacing, the initial deformation of exterior steel plates must be taken into consideration in determining the optimum stud spacing. In this context, finite element (FE) analyses on steel plates considering the initial shape imperfection are performed, and a design guideline to determine the stud and tie-bar spacing is proposed on the basis of numerous parametric studies.

确定 SCP 成员螺柱间距的简化公式

摘要 储罐中广泛使用的钢-混凝土复合板（SCP）是一种模块化结构构件，通过在两块外部钢板内浇筑混凝土制成。然而，混凝土的浇筑通常会产生非常高的压力，这可能会导致外部钢板的初始变形过大，并且所产生的变形会通过增加钢板的不稳定性而影响SCP构件的最终抵抗能力。然而，钢板变形对极限抗力评价的影响尚未得到系统的评价。尤其是钢板的极限抗力与螺柱间距密切相关，因此在确定最佳螺柱间距时必须考虑外部钢板的初始变形。
