This paper presents an approach to predicting the productivity of the concreting process based on a conducted quantitative research involving the recording of concreting at building construction sites in the city of Nis, Serbia. In the period of 20 months, 81 recordings of reinforced slabs on eight construction sites of buildings were observed and recorded. The total amount of poured concrete was 11951 m 3 and the total consumed time was 503 work hours. The factors that could impact productivity have been identified and a simulation model for predicting the productivity of the concreting process has been developed using Discrete Event Simulation and Agent Based Modelling. AnyLogic software package was used to develop the simulation model. Experiments were carried out and based on the obtained parameters the models are estimated. The proposed models can be useful in the planning stage and allow for more precise prediction of concreting productivity, thus benefiting the decision making and work flow prediction and improving the concreting process management in order to increase productivity, shorten the delays, and reduce costs.

“…Kim et al [6,7] discussed the technique to reduce the vertical deformation difference of columns by setting additional reinforcement to increase the axial stiffness of columns and proposed a lumped construction sequence analysis method for shortening the column of high-rise buildings. Han et al [8] proposed performance prediction and performance evaluation methods for the applied target technology. Cargnino and Taliano [9] discussed a compensation method that combines the effects of construction sequence and stiffness changes on time-related properties by taking a reinforced-concrete high-rise building in Italy as the background.…”

Connected super high-rise structure has a long construction period and significant time-dependent characteristics, so it is necessary to study its vertical deformation during construction. Taking an asymmetrical three-tower conjoined super high-rise structure as engineering background, the equivalent elasticity problem was analyzed by age-adjusted effective modulus method, and vertical deformation formula was deduced. A simplified model and a refined model of structure were established. The correctness of the deformation formula and modeling had been proven by comparing the dynamic characteristics and numerical simulation results. Based on the simplified model, the optimal construction plan of the conjoined super high-rise structure was discussed. Based on the deformation formula, the predeformation calculation method of the conjoined super high rise was studied, and the correctness was verified by numerical simulation. The results show that the largest vertical deformation of the connected structure occurs at the position of corridor, and an apparent mutation occurs here. Properly delaying the rigid connection timing between corridor and tower is beneficial to the control of the overall structural deformation difference and internal force. The predeformation analysis method proposed in this paper is correct and effective, which could offset the vertical deformation of the structure during the construction sequence.
