Abstract This work aims at describing the behavior of high-strength reinforced concrete (HSRC) beams under short-term ultimate loads with compressive strengths higher than 50 MPa. A plastic approach besides a cross sectional analysis is employed to primarily trace nonlinear response nineteen HSRC simply supported for which experimental results are available. proposed theoretical able acceptably...

the mean and variance of the lagrangian katz family of distribution (lkd), the basiclagrangian katz distribution of type i (lkd-i) and type ii (lkd-ii) are provided in an easy method.the recurrence relation between the non-central, central and factorial moments, and the recurrencerelation between moments and cumulants of lkd, lkd-i and lkd-ii are given. the first fourcumulants of lkd-i and lkd-...

Abstract Modeling of roll forming process sheet metal requires efficient treatment plastic deformations thin shells and plates. We suggest a new general approach toward constructing the governing equations bending an elastic‐plastic Kirchhoff plate on structural mechanics level. The generic function isotropic hardening law is formulated in terms variables, which are meaningful for material surf...

Pushover analysis is an efficient method for the seismic evaluation of buildings under severe earthquakes. This paper aims to develop and verify pushover methodology reinforced concrete frames. technique depends on a nonlinear representation structure by using SAP2000 software. The properties plastic hinges will be defined generating moment-curvature all frame sections (beams columns). verifica...

the development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. in petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. in this study, which is a...
