Abstract Analysing confined masonry (CM) with strengthening around the opening (analytical model) was conducted numerically. The variations were centric and eccentric doors an ratio of 16.93% 31.75%; windows ratios 10.16% 19.05%. This analysis aims to apply procedure for analysing CM models by using layered shell elements also comparing behaviour performance each model. frames modelled in SAP20...

A formula to estimate the yield displacement observed in the pushover analysis of coupled wall lateral force-resisting systems is presented. The estimate is based on the results of an analytical study of coupled walls ranging from 8 to 20 stories in height, with varied amounts of reinforcement in the reinforced concrete coupling beams and walls, subjected to first-mode pushover analysis. An exa...

In this paper, a global limit state function for load-carrying capacity of structural system is firstly set up, in which the margin of safety is the difference between the limit base shear of structural system and the total horizontal seismic action. To probabilistically assess the global seismic capacity of structure, a new point estimation method (PEM) for analyzing statistical moments of com...

This paper presents a detailed study of the damages and collapses suffered by various masonry churches in aftermath seismic sequence Central Italy 2016. The will first be analyzed then compared with numerical data obtained through 3D simulations eigenfrequency nonlinear static analyses (i.e., pushover). main purposes this are: (i) to create an adequately consistent sensitivity on several defini...

The direct modeling of masonry infill walls on many buildings, based damage recorded by various past earthquakes, has become increasingly necessary in order to identify the seismic behavior these elements, which constitute an important part reinforced concrete buildings. In this paper, several 3D models were analyzed nonlinear static (pushover) method, when ignoring, and considering, walls. fin...

A main challenge for performance-based seismic engineering is to develop simple, practical and precise methods for analyzing designed buildings and assessing existing structures to satisfy considerable performance objectives. Pushover analysis is a simplified nonlinear analysis technique that can be implemented for estimating the dynamic demands imposed on a structure under earthquake excitatio...

This paper presents the influence of gravity framing on collapse risk steel frame buildings with perimeter special moment frames (SMFs) designed in Turkey. For this, four- and eight-story have been considering related current specifications codes. Header end-plate connections are used for beam-to-column joints system. A nonlinear analytical model that simulates hysteretic behavior header is cal...

The paper presents a numerical study for the seismic assessment of the St James Church in Christchurch, New Zealand affected by the recent 2011 earthquake and subsequent aftershocks. The structural behavior of the Church has been evaluated using the finite element modelling technique, in which the nonlinear behavior of masonry has been taken into account by proper constitutive assumptions. Two ...

The structural damage due to recent seismic events in Nepal has led a dire need for studies considering soil-structure interaction (SSI) as the majority of designers still adopt conventional design principles. These damages may be result fixed base method’s failure take into account underlying soil properties. Post $$M_w$$ 7.8 Gorkha earthquake, revised National Building code NNBC 105:2020 clas...
