Abstract: In this paper, the analytical forms of the shapes of submerged funicular arches are expressed in terms of elliptic integrals. The initial radius of curvature at the apex is related to the water depth at the apex and the ...

Abstract: In this paper, the shear stiffness in the weaker direction of Z-core sandwich panels is studied. The recurrence condition is assumed, and the shear stiffness is derived from the first principle. The contact interaction ...

Abstract: A full-scale uniplanar completely overlapped tubular K(N) joint specimen is tested to determine the hot spot strains at the joint intersections for the verification of the finite-element (FE) model. The test results reveal ...

Abstract: A simple analytical approach based on the Rankine principle has been developed to determine the ultimate resistance of steel frames in fire. The proposed Rankine approach gives an approximation of the frames' fire resistance ...

Abstract: The aim of this paper is to study the stress concentration factors of doubler plate reinforced tubular T joints subjected to various types of basic loading such as axial tension, axial compression, and in-plane and ...

Abstract: A simple and direct analytical formula has been derived to determine the compressive resistance of steel columns subjected to fire conditions. The approach is based on the Rankine principle, which allows the strength and ...

Abstract: This paper presents a second-order elastic-plastic hinge method and a finite-element model for the analysis of plane frames in fire. Both methods are derived from the same two-node corotational beam element and are based ...

Abstract: Fire resistance of steel joints is always a major concern in the design of steel structures under extremely hazardous conditions. However, for circular hollow section (CHS) joints in fire conditions, little information is ...

Abstract: Quasi-brittle solids usually contain many cracks. When numerical methods are used, it is difficult to simulate all the cracks’ behaviors, especially when the crack propagation is included. To surmount the difficulty, a new ...
