This document presents a comparative study on the time period and frequency of full arch and vierendeel truss steel pedestrian bridges with spans of 40m, 50m, and 60m. Finite element analysis is performed using SAP 2000 software to analyze the bridges under dynamic excitation. The time history analysis is conducted according to IRC codes to determine the natural frequency and time period of different vibration modes. Tables show the calculated time periods and frequencies for the first 12 modes of both bridge types over the three spans. Charts compare the variation of time period and frequency with mode shape. The results show differences in the dynamic response of full arch bridges versus vierendeel truss bridges, and how responses change with increasing span length.

This document discusses a study on applying passive control techniques like tuned mass dampers (TMDs) to reduce vibrations in reinforced concrete (RC) bridges through nonlinear dynamic analysis. 3D models of box girder bridges with different spans were analyzed with and without TMDs using SAP2000 software. TMDs with mass ratios of 2%, 3%, and 4% were considered. Dynamic responses like natural period, base shear, displacements, and forces were compared for bridges with and without TMDs when subjected to ground motion records. Results showed that addition of TMDs decreased the natural frequency of bridges the most for the highest mass ratio of 2%, with decreases of up to 41.23% observed for different bridge
This document analyzes the effect of skew on stress resultants in T-beam bridges under various Indian Road Congress (IRC) loading conditions. T-beam bridge models with spans of 14m and varying skew angles from 0-45 degrees were modeled and analyzed using CSi Bridge software. The results show that bending moment, shear force, and torsion increase with higher skew angles and heavier loadings. Specifically, IRC AA tracked loading produces 10-15% higher bending moments than IRC 70R loading. IRC AA tracked and wheeled loadings also produce significantly different stress responses, with up to 40% variation. The analysis provides guidance on the behavior of skewed T-beam bridges under IRC standard loadings.

Comparative study on normal and skew bridge of psc box girdereSAT Journals
Abstract Nowadays the demand for high skew bridges has increased, and many bridge decks are built with some form of skew. The behavior of bridge is effected considerably with the presence of skew angle in bridge decks. In the present study an attempt has been made to study the skew bridge comparing with the normal bridge for skew angle 10, 20, 30, 40, 50. The finite element analysis is carried out for single span, two span and three span deck for dead load and moving load (IRC class 70R) loading using software SAP2000 ver.14. The results are presented in terms of displacement, bending moment and shear force. Keywords: Skew bridges, skew angle, PSC box girder, span length
The document discusses the design and construction of composite bridge piers made of steel pipes and concrete. Experimental tests on scaled pier models showed that the composite piers had higher deformation performance and more stable seismic behavior than conventional reinforced concrete hollow piers. The composite piers exceeded maximum deformation but had relatively small residual displacement after earthquakes. The analytical models of composite piers showed lower deformation performance than experimental results because they could not account for the contribution of ductile steel pipes and high-strength strands. A new construction method called Hybrid Slipform Method provides rapid construction and reduced labor for the composite piers.
Reduction of Ultimate Strength due to Corrosion - A Finite Element Computatio...CSCJournals
Bridge safety is of paramount importance in transportation engineering and maintenance management. Corrosion causes strength deterioration and weakening of aged steel structures. Therefore, it is a vital task to estimate the remaining strength of corroded steel structures in order to assure the public safety. Due to the economic constraints and increase of number of steel highway and railway bridge structures, it will be an exigent task to conduct tests for each and every aged bridge structure within their bridge budgets. Therefore, this paper proposes a method of evaluating the residual strength capacities by numerical approach and compares the non-linear FEM analyses results with their respective tensile coupon tests. Further, since it is not easy to measure several thousands of points, to accurately reproduce the corroded surface by numerical methods and to predict their yield and ultimate behaviors, a simple and reliable analytical model is proposed by measuring the maximum corroded depth (tc,max), in order to estimate the remaining strength capacities of actual corroded members more precisely.

IRJET - A Review on Seismic Behaviour of Floating Column and Transfer BeamIRJET Journal
This document reviews the seismic behavior of floating columns and transfer beams in buildings. It discusses how floating columns, which do not extend fully to the foundation, can negatively impact seismic performance by disrupting the load path. The document summarizes several past studies that have analyzed buildings with and without floating columns using structural analysis software. Response spectrum and time history analyses were used to compare seismic parameters like time period, base shear, displacements, and drifts. The studies found that buildings with floating columns generally have increased time periods, displacements and drifts compared to identical buildings without floating columns. However, base shear may be lower for buildings with floating columns. Proper design and reinforcement of transfer beams that support floating columns is emphasized.

IRJET- Analysis of Long Span Suspension Bridge under Wind Load and Moving LoadIRJET Journal
This document analyzes long span suspension bridges under wind and moving loads using SAP2000 software. Three bridge models were created with spans of 400m, 500m, and 600m. The bridges were analyzed for wind loads based on Indian and ASCE codes. Moving load analysis used Class AA tracked loads. Results showed time period and deck deflection increased with span while frequency decreased. Suspender forces were lower than sag cable forces. Maximum pylon displacement occurred in the 600m span bridge under wind loads. In conclusion, suspension bridge behavior depends strongly on span length, and wind loads govern perpendicular to the bridge direction.

This document discusses a study that uses nonlinear pushover analysis to analyze the behavior of bridges with different pier heights and span lengths when subjected to seismic loads. Six bridge models are created with varying pier heights (short vs long) and span configurations (equal vs unequal spans). The bridges are modeled in SAP2000 and analyzed using linear static, modal, and seismic analysis to determine dynamic properties. Pushover analysis is also used to investigate the nonlinear behavior and obtain performance points. Results show bridges with short piers and unequal spans have similar seismic performance but are more economical than those with long piers or equal spans.

Dynamic analysis of a reinforced concrete horizontal curved beam using softwareeSAT Journals
Abstract
Dynamic analysis of a reinforced concrete beam bridge, horizontally curved in plan is done using a finite element software. The
support conditions considered are simple supports. Dynamic loading in the form of moving vehicular load is taken into account
for the purpose of analysis. IRC Class AA type of vehicle is simulated on two lanes on the beam of span 31m, having a box type
cross-section. A parametric study is done varying the radius of curvature of the beam from 50 m to 250 m with the interval of 50
m to check the behavior of the beam. Various responses of the beam like bending moment, shear force, torsional moment and
deflection are calculated. The influence of a non-dimensional parameter L/R i.e. ratio of length of the beam to radius of curvature
of the beam is verified for the responses of the beam. From the results, it has been found that the responses i.e. the bending
moment, shear force, torsional moment and deflection of the beam decrease as the radius of curvature of the beam in increased.
Also, the responses of the beam increase as the L/R ratio is increased.
