Bearing or compressive strength capacity perpendicular to the grain of timber beams is a troublesome issue. Not only do many different load cases occur in practice that are not covered by structural timber design codes but also these codes provide only a basic provision and vary throughout continents. Code design rules require the standardized compressive or bearing strength to be determined by...

In Iran and some other countries, elastomer bearings in seat-type bridges are used with no sole/masonry plates and there is no positive connection between superstructure and substructure. Different codes have diverse provisions regarding the coefficient of friction (μ) between elastomer bearing and superstructure/substructure and also the design strength of shear keys (Vsk). Developing a finite...

The load on transport and logistics systems is increasing every year. This due to car park growth around the world. Thus, bridge structure durability an urgent task for bridge-building companies. study analyses contact deformation of spherical bearing elements through anti-friction polymer layer with different geometrical configurations recesses lubricant, i.e., annular grooves holes. material ...

Deflection is a key index to reflect the bearing capacity and operation situation of bridges. As existing measurements methods have their limitations, this paper tries introduce new method using suspension cable measure deflection This sets supports for dial meters by erecting main cables up longitudinal measuring points on bridge deck. The counterweights limit bars avoids horizontal disturbanc...

The purpose of this paper is to use static and dynamic load tests evaluate the mechanical performance a simply supported skew slab bridge its actual bearing capacity. Firstly, Midas Civil software used for theoretical simulation, secondly, deflection, strain, response key section are studied through tests. Finally, measured values compared analyzed. results show that: under load, relative resid...
