Abstract Structural engineers should appropriately design concrete structures to resist lateral loads. Determining the adequate system for resisting expected loads is important control building drift. Choosing appropriate usually conducted assuming predicted forces are applied completed buildings at one step which commonly known as ordinary analysis ( OA ). Nevertheless, these constructed seque...

Abstract Currently, there is no “timber moment frame structural system,” as the basic glulam beam‐to‐column connections (usually represented by bolted with slotted‐in steel plates) offer limited rotational stiffness such that they are usually treated pin connections. This paper proposes an innovative type of moment‐resisting connection reinforced long rods screwheads (LSRSs) and self‐tapping sc...

Abstract: A finite element model is verified accurate enough to simulate the static test of one reinforced-concrete frame with specially shaped columns subjected to the loss of a ground corner column. As the frame sustained loads primarily depending on the beam resisting mechanism in the test, four related parameters, namely the height of beam section, rebar ratio of beam, rebar ratio of slab a...

This paper presents quantitative information on the effectiveness of seismic retrofit solutions using bilinear oil dampers for seismically deficient existing tall steel buildings. For this purpose, a benchmark 40-story space moment-resisting frame building is studied that represents 1970s design practice in North America. Rigorous performance assessment based ASCE 41 recommendations reveals hig...

In this paper, optimum design of three-dimensional (3D) multi-story reinforced concrete (RC) structures is obtained using an improved version the plasma generation optimization (IPGO) algorithm. The reinforcing bars and geometry cross-sections are considered as discrete variables that chosen from a prearranged section database. objective function cost framework, steel concrete. moment shear fra...

In the present study, the reliability assessment of performance-based optimally seismic designed reinforced concrete (RC) and steel moment frames is investigated. In order to achieve this task, an efficient methodology is proposed by integrating Monte Carlo simulation (MCS) and neural networks (NN). Two NN models including radial basis function (RBF) and back propagation (BP) models are examine...

in this paper a new method based on strut-and-tie model (stm) is proposed to determine the shear capacity of simply supported rc deep beams and an efficiency factor for concrete with considering the effect of web reinforcements. it is assumed that, the total carried shear force by rc deep beam provided by two independent resistance, namely diagonal concrete strut due to strut-and-tie mechanism ...

In this paper, three precast concrete (PC) frames and one cast-in-situ reinforced-concrete (RC) frame were cast tested to investigate the load-resisting mechanisms of emulative PC with various reinforcing details resist progressive collapse. beams frames, top reinforcement was continuous without curtailment while bottom had different anchorage strength. Test results indicated that, in event mid...

The steel frame reinforced with steel shear wall is a lateral load resisting system and has higher strength and shear performance than the concrete shear wall system. Especially, using corrugated steel plates in these shear wall systems improves out-of-plane stiffness and flexibility in the deformation along the corrugation. In this paper, a cyclic loading test of this steel frame reinforced wi...
