We study the problem of combined bending and tension an isotropic plate containing a through crack by distributed moments forces at infinity in absence contact between faces external loads applied to but presence plastic zones its tips. also take into account phenomenon hardening material satisfying Tresca plasticity conditions form surface layer or hinge. By using complex potentials plane clas...

Moment resisting frames as one of the conventional lateral load resisting systems in buildings suffer from some limitations including code limitations on minimum span-to-depth ratio to ensure the formation of plastic hinges with adequate length at beam ends. According to seismic codes, in ordinary steel moment resisting frames the minimum span-to-depth ratios should be limited to 5 and in speci...

This study investigates the complex load-bearing mechanism of reinforced concrete tower large wind turbines through a structural model test. MTS electro-hydraulic servo loading system was used to load two models for push-out The ultimate bearing capacity found be 8.894 kN. test findings revealed that top is subjected unilateral shear as horizontal increases. As result, strain in compression zon...

Although experimental studies have proven as the most effective method, its high cost has provoked researchers to seek alternative approaches. The increase in computational power 21st century provides opportunity numerically model with various programs. This study examines comparison of force-based element and displacement-based columns using nonlinear fiber elements. Within scope study, OpenSe...

Abstract This study investigates nonlinear modeling and verification of a reinforced concrete element using the fiber section method. At first, theory related to approach hysteresis models used for cyclic analysis is given. Then, column tested previously in literature modeled simulation results are compared with test results. An acceptable approximation made utilizing only few input parameters:...

This study mainly presented a pseudo-static experiment on two full-scale square CFST short columns with the cross-sectional width of 600 mm under combined constant axial load and cyclic lateral load. The seismic performance were investigated. Meanwhile, plastic hinge length specimens was discussed. test results that suffered bend-shear failure. local buckling steel tube occurred at end core con...

A probabilistic model is devised for predicting the plastic hinge lengths (PHLs) of RC columns. Seven existing parametric models are evaluated first using a comprehensive database comprising PHL measurements from 133 column tests. It observed that performances these seven fair (as opposed to strong), and their predictions bear significant uncertainties. novel technique combine them into weighte...
