Settlement of Construction Dispute in Building Bridge through the Indonesian National Arbitration Agency (Bani)

In a construction work contract, legal disputes often occur during the implementation of the construction work contract, because there are achievements that are late and cannot satisfy one of the parties in the contract. Construction disputes have an impact on legal issues that result in time, cost losses and hinder the contribution of the construction sector in economic growth. The growth of the construction market in the era of globalization is also accompanied by high levels of legal disputes. With the issuance of the Law No. 2 of 2017 regarding Construction Services, it is hoped that problems relating to construction disputes will be more quickly resolved.

A frequency domain model for analysing vibrations in large-scale integrated building–bridge structures induced by running trains

Integrated building–bridge structures are increasingly common in high-speed railway stations, where the elevated track floor is directly subjected to train–track dynamic forces that result in excessive vibrations. The common methods of predicting the train-induced vibrations in large-scale IBBS are implemented in the time domain and can have prohibitively long computation times. This paper presents a frequency domain model for the vibration analysis of large-scale IBBS, with the aim of reducing the computation time while retaining sufficient accuracy. The model consists of three coupled subsystems: train, track, and IBBS. The train and track subsystems are investigated analytically, and the IBBS subsystem is solved numerically using a finite element method. The receptance technique is introduced to obtain the wheel/rail force. The force transmitted to the floor slab is treated as the vibration source of the IBBS subsystem. The simulated vibration levels in the IBBS subsystem are compared with those obtained from in situ measurements, and a good agreement is observed in terms of both magnitude and frequency dependence. The vibration responses of the IBBS subsystem at different locations of the track floor and the waiting floor are compared, and the influence of the track position is investigated. Finally, a parametric analysis is conducted with the aim of formulating anti-vibration measures, in which the carbody acceleration, rail displacement, and ballast acceleration are considered as key indicators. The force transmission, vibration transmission and IBBS vibrations are also investigated. The results indicate that using a ballast mat and enlarging the column cross-section are the two most promising measures for reducing the vibration levels.

RAILROAD SPACE-PLANNING FORMATION IN A LARGE CITY (ZLOBINO, KRASNOYARSK CASE STUDIES)

The article presents research results on space-planning links formed by the railroad. The typology and main characteristics are described. The approach to the comprehensive analysis is shown on the example of Zlobino railroad in Krasnoyarsk. The approach is used for restoration of town-planning structure by means of the building-bridge model.

INHABITED BRIDGE OF THE XX CENTURY

This article shows the formation process of inhabited bridge during the twentieth century. First building-bridge was erected in 1962. It is Marin County Civic Center by Frank Lloyd Wright. In 1991 Stock Exchange was constructed in London by SOMs project. It is first square-bridge. In 1997 first inhabited bridge of еру twentieth century was erected in Moscow.
