Introduction In modern engineering practice [1–5], ensuring the stability and safety of buildings and structures under high-intensity dynamic loads is an extremely important task.
Thermal effects (Fig. 6) caused significant damage to the floor slabs (delamination of the concrete protective layer) and destroyed the finishes and internal building engineering networks.

The implementation of these methods in engineering practice requires solving the problem of reliable identification of the setting time by the results obtained by various control methods.
The assessment objectification of the transition stages of structural formation based on the measurement of these properties and, as the next step, the algorithmization of determining the setting time by experimental data present practical interest to civil engineers.

During the seismic emergency the authors, in collaboration with the Civil Protection Department as part of the ReLUIS activities, have carried out usability inspections, analysing also the case study described in this paper.
After the recent seismic shocks (August 24 and of October 30, 2016), the authors have been involved in many inspections as part of the ReLUIS activities in accordance to the Italian Civil Protection Department, with the aim of evaluating the usability of public buildings.

Research on Secondary Moment of Prestressed Slab-Column Structure Nan Guo1, a, Hua Li1, b and Yihong Guo2, b 1College of Civil Engineering, Northeast Forestry University, Harbin 150040 China 2College of Aerospace and Civil Engineering, Harbin Engineering University, Harbin 150001 China atumuguonan@163.com,blihua7515@163.com,cgyhhrb@hotmail.com Key words: Slab-Column Structures; Secondary Moment; Finite Element Analysis; Reasonable Design Abstract.
Because of prestressed slab-column structure’s prominent advantage, it has become a structural system with widely application prospect recognized by the civil engineering circle [2].
In preliminary design of prestressed member, the effect of secondary is often considered by Engineers through multiplying empirical coefficient, which is 1.2 in mid-span and 0.9 in support [5].
The ratio of secondary moment and external load moment in the slab-column structure shown in Fig. 2 is given to explain the different effect secondary moment in different moment control section on the structure, and it can be served as reference for engineers.
