Abstract: This paper presents a simplified approximate analysis of the overall collapse of the towers of World Trade Center in New York on September 11, 2001. The analysis shows that if prolonged heating caused the majority of columns ...

Abstract: The addendum presents the responses to several questions on a preliminary version (which arrived too late for publication as part of the paper). The questions deal with the aircraft impact at a higher floor of the World ...

Abstract: Prestress loss of anchor cables can cause a change in the internal force for the support structure of a foundation pit or slope, which may cause engineering accidents. The coupling effect between an anchor cable and the ...

Abstract: Teleoperation rendezvous and docking (RVD) can be used as a supporting technology for unmanned spacecrafts, or as a technology to dock the chaser with a noncooperative target. Teleoperation RVD has attracted little attention ...

Abstract: The Silk Road pattern (SRP) is a well-known teleconnection pattern along the upper-level westerly jet over the Eurasian continent during boreal summer. The SRP has experienced an interdecadal change around the late 1970s. ...

Abstract: Concrete creep is related to not only loading age and holding time but also curing temperature and humidity. To investigate the influences of curing temperature and humidity on creep performance, tensile creep tests of ...

Abstract: Experiments on size effect on the failure loads of sandwich beams with PVC foam core and skins made of fiber-polymer composite are reported. Two test series use beams with notches at the ...

Abstract: Despite impressive advances, the existing constitutive and fracture models for fiber-reinforced concrete (FRC) are essentially limited to uniaxial loading. The microplane modeling approach, which has already been successful ...
