实施行政许可法任重道远——访市政府法制办主任徐强

行政许可法从本月1日起已在全国正式施行.本市政府方面的实施准备工作好了没有?本刊记者带着这一问题,专门采访了市政府法制办主任徐强. 总的说,第一阶段的工作目标已经完成,本市7月1日实施行政许可法的准备工作按照时间节点都已就绪.但是,还有若干后续工作要继续抓紧去做.

In-Plane Creep Buckling of Concrete-Filled Steel Tubular Arches

The creep-induced deformation of the arch rib of concrete-filled steel tubular （CFST） arches under a sustained load can increase the bending moment, which may lead to earlier stability failure called creep buckling. To investigate the influences of concrete creep on the buckling strength of arches, a theoretical analysis for the creep buckling of CFST circular arches under distributed radial load is performed. The simplified Arutyunyan-Maslov （AM） creep law is used to model the creep behavior of concrete core, and the creep integral operator is introduced. The analytical solutions of the time-dependent buckling strength under the sustained load are achieved and compared with the existing formula based on the age-adjusted effective modulus method （AEMM）. Then the solutions are used to determine the influences of the steel ratio and the first loading age on the creep buckling of CFST arches. The results show that the analytical solutions are of good accuracy and applicability. For CFST arches, the steel ratio and the first loading age have significant influences on creep buckling. An approximate log-linear relationship between the decreased degrees of the creep buckling strength and the first loading age is found. For the commonly used parameters, the maximum loss of the buckling strength induced bv concrete creen is close to 40%

离别情依依

近段时间以来，天气骤然变冷，为即将到来的离别平添几分凉意。当一个人静静地坐在电脑旁，听凭窗外怒吼的狂风冷雨，闲适中总央杂着些淡淡的伤感。毕竟，对于许多战友来说，在警营的日子已经屈指可数；作为战友，纵使心中有千般不舍、万般无奈，却只能通过文字来抒发，为即将离别的朋友送去一缕祝福：愿他们一路顺风。
