the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

(5) The limited access zone shall remain in place until the wall is adequately supported to prevent overturning and to prevent collapse unless the height of wall is over eight feet, in which case, the limited access zone shall remain in place until the requirements of paragraph (b) of this section have been met. (b) All masonry walls over eight feet in height shall be adequately braced to preve...

A prefabricated frame–shear wall structure is a major in an assembled building. To find method of connecting shear and columns that can both reduce the amount wet work required maintain adequate stiffness, we propose to vertical frame using rectangular concrete-filled steel tube keys (RCFSTKs). Static tests cast-in-place without with RCFSTKs were conducted compare their seismic performance. The...

The main purpose of this paper was to use a combination of Energy-based design method and whale algorithm (WOA), hereinafter referred to as E-WOA, to optimize steel moment frames and improve the seismic performance. In E-WOA, by properly estimating the seismic input energy and determining the optimal mechanism for the structure, steel frames are designed based on the energy balance method; acco...

abstract to resist lateral loads in concrete buildings, usually systems such as flexural frame, shear wall or their combinations are used. using x form of cable bracing in order to strengthen concrete buildings is a new method. this system is more economical compared with the other systems due to cables low weight, high tensile resistance, easy performance and less maintenance problems. in this...

Laboratory experimental data is often erroneous. This error is more apparent in data obtained from testing of anisotropic composite materials such as masonry wall panels. In this paper data colleted from the laboratory tests of masonry panels is presented. Methodologies for reducing (correcting) error in laboratory tested data are discussed. The concept of stiffness/strength corrector to model ...

Disassembling brick wall pieces into sections and constructing masonry buildings with disassembled (DBWSs) can reduce construction waste production at source help achieve carbon peak neutrality. A finite element model (FEM) for typical MSBD is established based on the calibrated analysis method to evaluate seismic performance of structures built (MSBD). Subsequently, ground acceleration selecte...

This paper presents an experimental program dealing with the shear strengthening with FRP systems of URM walls built with concrete and clay units. Ten concrete and five clay masonry panels, strengthened with FRP composites in the form of laminates and rods, and stainless steel, were loaded along the wall diagonal to observe their shear performance. The dimension of the concrete masonry panels w...
