Experimental Research on Bending Bearing Capability of Grouted Double Mortise-Tenon Joint for Prefabricated Metro Station Structure
نویسندگان
چکیده
The grouted mortise-tenon joint, invented as the connection between large prefabricated elements, is most important component in underground structures. This paper conducts analysis of load-carrying capacity performance and failure mode with 1 : prototype test key working direction different double joint types for metro station. resistance moment developed used to analyze bending bearing characteristic curve, corresponding results each stage curve are described detail. In addition, double-tenon joints under load conditions compared. clarify ultimate variable characteristics increase axial explain stage. It also found auxiliary pretightening device helpful delay appearance cracks improve capacity, especially when it set on tension side. research have application value design station

Withdrawal, shear, and bending moment capacities of round mortise and tenon timber framing joints
Many forest stands in this country as well as in numerous underdeveloped countries, are overstocked with small-diameter trees (Wolfe 2000, Wolfe and Moseley 2000). These trees pose both a health hazard and a fire hazard to the forests, and excess stems should be removed, but presently they have too little market value to justify their removal. Before these stems are utilized, value-added produc...
متن کاملSpace Station Alpha Joint Bearing
Perhaps the most critical structural system aboard the Space Station is the Solar Alpha Rotary Joint which helps align the power generation system with the sun (Figure 1). The joint must provide structural support and controlled rotation to the outboard transverse booms as well as power and data transfer across the joint. The Solar Alpha Rotary Joint is composed of two transition sections and a...

متن کاملSimulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7
In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied. The heat release rate is based on a quadratic f...
