Steel-glulam structure is a new type of composite structure,glulam have lateral support effect on steel plate, that can prevent premature buckling of steel plate and improve the stability of steel structure. In order to study the influence of column’s cross-section form on the seismic performance of steel-glulam composite beam-to-column exterior joint, the column’s cross-section form was taken as the basic variable (glulam rectangular section , H-beam section and H-beam-glulam rectangular section were used respectively). The pseudo-static tests of three composite beam-to-column joints were carried out to observe the different failure modes, and obtain the mechanical performance indexes. The experiment results demonstrated that: The energy dissipation capacity of beam-to-column exterior joint composed of glulam column was the worst, the ultimate bearing capacity and stiffness were the lowest. The ultimate bearing capacity of the exterior joints formed by the H-beam column and the H-beam-glulam composite column were both high, and their ductility coefficients were similar, while the former had better energy dissipation capacity.

Along with the growth of the population of a city, the need for the availability and accessibility of green areas for all population categories, regardless of age, financial capabilities, legal requirements, time, physical barriers, and most importantly — distance, increases, as green areas are important for maintaining physical and mental health of city residents. In Lviv, the area of public green areas per inhabitant significantly exceeds state norms. However, due to the uneven distribution of these areas in the city’s structure, some of the residents have problems with accessing them. Proposals of the development of the city’s green areas do not account for accessibility, which makes it impossible to improve it in the future due to the impossibility of reserving land for the development of such greened zones. In order to equalize the anthropogenic load and ensure that all residents have access to natural areas, an assessment of the territory of the city of Lviv was carried out in accordance with the green area pedestrian accessibility standard. Zones with an urgent need for the development of public-use green areas use were identified and methods of solving of this problem were proposed.

The author analyses legal issues of naval presence in the world ocean in the context of United Nations Convention on the Law of the Sea (1982) in terms of striking balance between doctrines of freedom of the sea and restricted access.

Military operations at sea remain to be prominent. UNCLOS does provide for naval presence in the world ocean as it isessential not only for defense and protection of interests of coastal nations, but also to perform their treaty obligations. The burden to enforce law and order at sea rests on large naval fleets and it remains to be so in foreseeable future.

The paper presents methods of determining the location of cost buffers and corresponding contingency costs in the CPM schedule based on its work breakdown structure. Application of correctly located cost buffers with appropriately established reserve costs is justified by the common overrunning of scheduled costs in construction projects. Interpolated cost buffers (CB) as separate tasks have been combined with relevant summary tasks by the starttostart (SS) relationship, whereas the time of their execution has been dynamically connected with the time of accomplishment of particular summary tasks using the “paste connection” option. Besides cost buffers linked with the group of tasks assigned to summary tasks, a definition of the cost buffer for the entire project (PCB) has been proposed, i.e. as one initial task of the entire project. Contingency costs corresponding to these buffers, depending on the data that the planner has at his disposal, can be determined using different methods, but always depend on the costs of all tasks protected by each buffer. The paper presents an exemplary schedule for a facility and the method of determining locations and cost for buffers CB and PCB, as well as their influence on the course of the curve illustrating the budgeted cost of work scheduled (BCWS). The proposed solution has been adjusted and presented with consideration of the possibilities created by the scheduling software MS Project, though its general assumptions may be implemented with application of other similar specialist tools.
